---|
| 26 | ---------------------------- |
---|
| 27 | - G4CashKarpRKF45: deleted un-needed duplicate (and unused) instance variable |
---|
| 28 | 'fNumberOfVariables', already defined in G4MagIntegratorStepper. (J.Ap.) |
---|
| 29 | - Some code cleanup. |
---|
| 30 | |
---|
| 31 | December 7th, 2007 J.Apostolakis & T.Nikitina - field-V09-00-03 |
---|
| 32 | ----------------------------------------------- |
---|

| 45 | August 21st, 2007 T.Nikitina - field-V09-00-01 |
---|
| 46 | ------------------------------- |
---|
| 47 | - Fix to DistChord() method for Helical Steppers: adopt 'special' case |
---|
| 48 | also for Ang<2pi not only for Ang<pi; use cos() in place of tan(), to |
---|
| 49 | improve CPU performance. |
---|
| 50 | - Improved AdvanceHelix() to be able to make half step and full step |
---|
| 51 | in one call. |
---|
| 52 | - In G4HelixMixedStepper added possibility to call different steppers for |
---|
| 53 | small steps and add some statistics how offen different steppers are called. |

---|
| 387 | |
---|
| 388 | Dec 12th, 2002 G. Cosmo - field-V04-01-06 |
---|
| 389 | --------------------------- |
---|
| 390 | - Moved unused variable 'nStpPr' to debug section in G4MagIntegratorDriver.cc, |
---|
| 391 | method AccurateAdvance(). |
---|
| 392 | |
---|
| 393 | Dec 06th, 2002 G. Cosmo - field-V04-01-05 |
---|
| 394 | --------------------------- |
---|
| 395 | - Merged changes by Makoto for migration to new G4ApplicationState in |

| 398 | Nov 29th, 2002 J. Apostolakis - field-V04-01-04 |
---|
| 399 | --------------------------------- |
---|
| 400 | Further fixes for unitialised variable - in other steppers: |
---|
| 401 | G4ExplicitEuler, G4ImplicitEuler, G4ImplicitEuler |
---|
| 402 | |
---|
| 403 | Large memory leak fix for G4ImplicitEuler, small for ExplicitEuler. |

| 406 | Nov 20th, 2002 J. Apostolakis - field-V04-01-03 |
---|
| 407 | --------------------------------- |
---|
| 408 | Further fixes for unitialised variables: |
---|
| 409 | |
---|
| 410 | * G4MagIntegratorStepper |
---|
| 411 | - Created instance variables for number of Integration, State variables |
---|
| 412 | |
---|
| 413 | * G4MagErrorStepper |
---|
| 414 | - Utilise number of State variables to initialise full state of Output. |
---|
| 415 | |
---|
| 416 | * G4Mag_SpinEqRhs |
---|
| 417 | - Initialise the values of dydx that we do not update. |
---|
| 418 | |
---|
| 419 | Note: Undoing these changes and the ones below would enable the user to see |
---|
| 420 | if undefined values are used in variables that he/she expects to |
---|
| 421 | have integrated. |
---|
| 422 | BUT the fix assists us to find truly undefined values elsewhere |
---|
| 423 | -- if they exist -- using valgrind. |
---|
| 424 | |
---|
| 425 | Nov 9th, 2002 J. Apostolakis - field-V04-01-02 |
---|
| 426 | --------------------------------- |
---|
| 427 | Fixes to address use of uninitialised variable in seting values of FieldTrack |
---|
| 428 | (this was done by design, but was neither ideal or always well-behaved.) |
---|
| 429 | Changed: |
---|
| 430 | |
---|
| 431 | * G4MagIntegratorDriver |
---|
| 432 | - Added instance variables for number of Integration, State variables |
---|
| 433 | - Initialise all State variables of Output with values from initial variables. |
---|
| 434 | - Only the Integration variables will be integrated |
---|
| 435 | |
---|
| 436 | * G4ClassicalRK4 and G4MagErrorStepper |
---|
| 437 | - Copy the initial time to intermediate and output C-vectors, |
---|
| 438 | in order to provide a zero-eth estimate value. |
---|
| 439 | Note1: Should clean-up this fix, making it similar to Driver (above) |
---|
| 440 | Note2: Should *not* be used for time varying field unless created |
---|
| 441 | with at least 8 integration variables |
---|
| 442 | --------------------------------- |
---|
| 443 | G4ChordFinder.cc |
---|

---|
| 445 | which is does not update the Unconstrained step estimate (state) |
---|
| 446 | - Added instance variables to store number of calls and chord-trials |
---|
| 447 | and new print method for 'debugging' |
---|
| 448 | |
---|
| 449 | G4Mag_UsualEqRhs.cc |
---|
| 450 | - Attempted approximations for speedup *overwritten* by full inverse sqrt. |

---|
| 459 | - (Only changed and tagged test subdirectory) |
---|
| 460 | Changed tests to use the new method SetChargeMomentumMass of |
---|
| 461 | PropagatorInField in order to be ready for its full use in |
---|
| 462 | G4PropagatorInField. |
---|
| 463 | (A key problem at end-July was this non-preparedness of the unit tests.) |
---|
| 464 | |
---|

---|
| 536 | - G4MagIntegratorStepper |
---|
| 537 | * Changed RightHandSide from a virtual method to an inline (non-virtual) |

| 539 | |
---|
| 540 | Mar 28th, 2002 J. Apostolakis - field-V04-00-01 |
---|
| 541 | ----------------------- |
---|
| 542 | - Fixed LinearStep in G4MagHelicalStepper (expected unit direction), |
---|
| 543 | that had not been updated for new integration variable (momentum). |
---|
| 544 | --> found in testing helical steppers in BaBar setup, |
---|
| 545 | in region of negligible field. |
---|
| 546 | |

---|
| 577 | ----------------------- |
---|
| 578 | - Fixed interface to virtual functions in the inheritance chain. |
---|
| 579 | Added 'virtual' qualifier to destructor and GetFieldValue() for subclasses |
---|
| 580 | of G4Field which may act as base class for user-defined fields. |
---|
| 581 | Modified files: G4MagneticField.hh, G4UniformElectricField[.hh.cc], |
---|
| 582 | G4UniformMagField.hh. |
---|
| 583 | - G4ChordFinder.cc: the unphysical curve length exception has been moved to |
---|
| 584 | inside #ifdef G4DEBUG_FIELD. Other #ifdef renamed to G4DEBUG_FIELD. |
---|
| 585 | - G4LineSection[.hh.cc]: correction for A=B when the distance from P to A |

---|
| 588 | Nov 28th, 2001 J. Apostolakis - field-V03-02-07 |
---|
| 589 | ------------------------------ |
---|
| 590 | G4FieldManager |
---|
| 591 | - Added fFieldChangesEnergy data member and get/set methods |
---|
| 592 | ( required to allow transportation to know how to calculate end-time, |

| 593 | enabling the integration of time only for electric fields. ) |
---|
| 594 | |
---|
| 595 | Nov 28th, 2001 J. Apostolakis - field-V03-02-06 |

---|
| 605 | Nov 21st, 2001 G. Cosmo - field-V03-02-05 |
---|
| 606 | ------------------------ |
---|
| 607 | - Protected verbose warnings with G4FIELD_DEBUG flag in G4ChordFinder.cc |
---|
| 608 | (V.Grichine). |
---|
| 609 | - Replaced G4DEBUG with G4DEBUG_FIELD in G4MagIntegratorDriver.cc. |
---|
| 610 | - Updates to unit test field02. |
---|
| 611 | |
---|
| 612 | Nov 13th, 2001 G. Cosmo - field-V03-02-04 |

---|
| 616 | |
---|
| 617 | Nov 9th, 2001 J. Apostolakis - field-V03-02-03 |
---|
| 618 | ----------------------------- |
---|
| 619 | Motivated by the use case of an Electric Field, |
---|
| 620 | - in order to achieve reasonable accuracy in time integration, |
---|
| 621 | - and to enable fields that vary with the global time) |
---|
| 622 | we (John Ap. and V. Grichine) changed the following: |
---|
| 623 | |
---|
| 624 | - Modified G4Field to allow the time in the GetFieldValue method |
---|
| 625 | - as 4th component of the "position" array. |
---|
| 626 | |
---|
| 627 | - Modified EquationOfMotion to provide the time to the GetFieldValue method |
---|
| 628 | of G4Field |
---|
| 629 | * as the 4th component of a position / time 4-array |
---|
| 630 | * in place of only position as a 3-arry |
---|
| 631 | |
---|
| 632 | - Added the global time as variable to be integrated over in the |
---|
| 633 | case of an Electric Field |
---|
| 634 | |
---|
| 635 | Support for these modifications is required in G4Transportation. |
---|
| 636 | |
---|
| 637 | (Better support will require either |
---|
| 638 | - a modification in G4FieldTrack to indicate whether the time has been |
---|
| 639 | integrated or not. |
---|
| 640 | - or additionally making the time calculation a property of G4FieldTrack, |
---|
| 641 | bring in code to do it in from G4Transportation.) |
---|
| 642 | |
---|
| 643 | |
---|
| 644 | Nov 8th, 2001 J. Apostolakis - field-V03-02-02 |
---|
| 645 | ------------------------ |
---|
| 646 | - Introduced several changes in G4MagIntegratorDriver. |
---|
| 647 | |
---|
| 648 | It now respects its minimum driver step size in AccurateAdvance. |
---|
| 649 | * whereas before it did not. |
---|
| 650 | |
---|
| 651 | Modified maximum number of steps, lowering by factor of 10. |
---|
| 652 | -> it should reduce the time spent integrating low energy particles, |
---|
| 653 | in some cases where it is unneccessary. |
---|
| 654 | |
---|
| 655 | Protected printing of (nearly?) all warnings with a G4DEBUG_FIELD #ifdef. |
---|
| 656 | |
---|
| 657 | |
---|
| 658 | Nov 05th, 2001 G. Cosmo - field-V03-02-01 |

---|
| 663 | ------------------------------ |
---|
| 664 | Tagged last change. |
---|
| 665 | This tag is utilised in transport-V03-02-01 (which requires it). |
---|
| 666 | |
---|
| 667 | Aug 16th, 2001 J. Apostolakis |
---|
| 668 | ------------------------------ |
---|
| 669 | G4ChordFinder: |
---|
| 670 | Added method to erase/reset the state of the StepEstimate. |
---|
| 671 | This is unwanted internal state that was carried between tracks and |
---|
| 672 | events as a side effect. |
---|
| 673 | |
---|
| 674 | Calling this at the start of each track, it is now possible to |
---|
| 675 | eliminate a non-repeatability that was possible due to this. |
---|
| 676 | ( It has been observed in particular in vaccuum. ) |
---|
| 677 | |
---|

---|
| 685 | parameters. |
---|
| 686 | |
---|
| 687 | - Updated testPropagateSpin (it now compiles), |
---|
| 688 | and some outputs of testPropagateMagField (1 to 5) |
---|
| 689 | |
---|
| 690 | |
---|

| 700 | Mar 23rd, 2001 J. Apostolakis - field-V03-00-04 |
---|
| 701 | ------------------------------ |
---|
| 702 | - Electric Field unit test now works: test runs until completion. |
---|
| 703 | Test outputs saved (on Linux). |
---|
| 704 | |
---|
| 705 | - Fixed src/G4UniformElectricField.cc to set correct field components |
---|
| 706 | (compatible with Equation of Motion |
---|
| 707 | G4EqMagElectricField ) |
---|
| 708 | |
---|
| 709 | - Tidied G4FieldTrack |
---|

---|
| 715 | ------------------------------ |
---|
| 716 | - Fixed (hacked) CashKarp to work using Auxiliary Stepper. |
---|
| 717 | |
---|
| 718 | - Modified G4MagIntegratorStepper |
---|
| 719 | to use pointer to G4EquationOfMotion |
---|
| 720 | instead of G4Mag_EqRhs |
---|
| 721 | |
---|
| 722 | - Design iteration appears neccessary |

---|
| 725 | ------------------------------ |
---|
| 726 | - Fixed G4MagHelicalStepper::AdvanceHelix for momentum, allowing |
---|
| 727 | the possibility of (correct) use of all Helical Steppers. |
---|
| 728 | |
---|
| 729 | - test/testProElectroMagField.cc updated for momentum. |

---|
| 734 | ------------------------------ |
---|
| 735 | - Tagging the modification of several classes to integrate in momentum*c_light |
---|
| 736 | instead of velocity. |
---|
| 737 | Reason for change: Velocity integration can result in superluminar |
---|
| 738 | velocities, due to arithmetic inaccuracies. |
---|
| 739 | Classes modified: |
---|
| 740 | G4FieldTrack, (Changed components 3,4,5 of SixVector to Momentum, |
---|
| 741 | G4Mag_EqRhs, G4Mag_UsualEqRhs, G4EqMagElectricField |

---|
| 745 | - Modified several classes to integrate in momentum instead of velocity. |
---|
| 746 | |
---|
| 747 | G4FieldTrack: |
---|
| 748 | Changed components 3,4,5 of SixVector to Momentum, |
---|
| 749 | Modified constructor |
---|
| 750 | Added energy calculation to "LoadFromArray" method |
---|
| 751 | GetEnergy method is now implemented. |
---|
| 752 | Deleted obsolete (old) method names for Curve and Position. New have "Get" |
---|
| 753 | |
---|
| 754 | G4ChordFinder |
---|
| 755 | Renamed old-method names of Field Track to new ones. |

| 758 | ------------------------- |
---|
| 759 | |
---|
| 760 | - Minor fix to G4MagneticField.hh: added explicit call to G4Field() in |

---|
| 763 | Nov 20th, 2000 G. Cosmo - field-V02-00-02 |
---|
| 764 | |
---|
| 765 | - Fixes to remove warnings from "-Wall -ansi -pedantic" g++ compiler options: |
---|
| 766 | o commented out variables declared and not used. |
---|
| 767 | o fixed declaration of variables used before being initialised. |
---|
| 768 | o fixed order of initialisation of member data in constructors. |
---|
| 769 | o fixed usage of unsigned-int (size_t) for array indeces. |

---|
| 771 | Nov 9th, 2000 G. Cosmo - field-V02-00-01 |
---|
| 772 | |

---|
| 776 | Nov 1st, 2000 G. Cosmo - field-V02-00-00 |
---|
| 777 | |
---|
| 778 | - QA code revision and cleanup (+fixes from CodeWizard filtering): |
---|
| 779 | o Added (private) declarations of copy constructor and assignment operator |
---|
| 780 | where needed. |
---|
| 781 | o Added "const" qualifier to accessor methods, wherever needed. |
---|
| 782 | o Added equality check on operator= where needed. |
---|
| 783 | o Made destructor "virtual" for classes having virtual methods, |
---|
| 784 | wherever missing. |
---|
| 785 | o Changed virtual functions to non-inline wherever's the case. |
---|
| 786 | o Changed return value to be "const" pointer to functions: |
---|
| 787 | - G4EquationOfMotion::GetFieldObj() |
---|
| 788 | - G4FieldManager::GetDetectorField() |
---|
| 789 | - G4MagIntegratorDriver::GetStepper() |

| 792 | o General cosmetics |
---|
| 793 | |
---|
| 794 | Jun 2nd, 2000 J. Apostolakis |
---|
| 795 | - G4FieldManager[.hh.icc] |
---|
| 796 | o Added DeltaIntersection and DeltaOneStep to FieldManager: added |
---|

---|
| 800 | |
---|
| 801 | include/G4FieldManager.hh,icc |
---|
| 802 | o Moved Delta Intersection and Delta One Step to FieldManager |
---|
| 803 | (from Propagator in Field), to allow them to differ over the detector. |
---|
| 804 | |
---|
| 805 | May 11th, 2000 J. Apostolakis - field-V01-01-02 |
---|
| 806 | |
---|
| 807 | - G4ChordFinder[.hh.cc] |
---|
| 808 | o Modified method for finding new trial step. |
---|
| 809 | New method assumes a quadratic relationship between step-length and d_chord: |
---|
| 810 | d_chord proportional to step-lenght ^ 2 |
---|
| 811 | o Added two small refinement in order to avoid unneccesary extra step due to |
---|
| 812 | small numerical inaccuracies in estimation: |
---|
| 813 | FindNextChord |
---|
| 814 | to first step use (1-0.001) * last-step-estimate |
---|
| 815 | New Step: |
---|
| 816 | to subsequent step use trial_step = 0.98 * estimate |

---|
| 823 | May 9th, 2000 J. Apostolakis - field-V01-01-01 |
---|
| 824 | |
---|
| 825 | - G4MagErrorStepper: |
---|
| 826 | Modified DistChord to check whether the chord endpoint are the same point. |
---|
| 827 | |
---|
| 828 | - G4RKG3_Stepper: |
---|
| 829 | Deleted error message from StepNoErr, as it is used in Stepper. |
---|
| 830 | |
---|
| 831 | - G4MagIntegratorDriver: |
---|
| 832 | Changed the condition for the debug output (~cosmetic) |

---|
| 837 | - Reorganised comments for the Software Reference Manual. |
---|

| 841 | April 13th, 2000 J. Apostolakis - field-V01-01-00 |
---|
| 842 | |
---|
| 843 | - Modified signature to function DumbStepper() in classes: |
---|
| 844 | G4HelixExplicitEuler, G4HelixHeum, G4HelixImplicitEuler, |
---|
| 845 | G4HelixSimpleRunge and G4MagHelicalStepper. |
---|
| 846 | - Modified signature and implementation of function MagFieldEvaluate() |
---|
| 847 | in G4MagHelicalStepper, to use Field (as ThreeVector) in place of dydx. |
---|
| 848 | - Made Richardson extrapolation optional (it is unclear if |
---|
| 849 | it offers benefit) in G4MagHelicalStepper. |
---|
| 850 | - Updated unit test testPropagateMagField and reference output. |
---|
| 851 | - G4LineSection: fixes to prevent divisions by 0. and sqrt(<0) |
---|
| 852 | (V.Grichine). |

---|
| 861 | For negative or very small curve lengths (h) we suppress writing an error |
---|
| 862 | (about the distance of endpoints being further than the curve length), |
---|
| 863 | as it is meaningless. |

| 870 | July 6th, 1999 J. Apostolakis - field-01-00-07 |
---|
| 871 | |
---|
| 872 | These fixes and those in field-01-00-06 and field-01-00-06a all come |
---|
| 873 | from the need to cope with the imprecision of the integration, and its |
---|
| 874 | interaction with paths that are rather straight. |
---|
| 875 | |
---|
| 876 | G4MagIntegrationDriver: |
---|
| 877 | i) AccurateAdvance now that the chord distance is smaller than the curve len- |
---|
| 878 | gth (times 1+epsilon). |
---|
| 879 | |
---|
| 880 | ii) OneGoodStep and QuickAdvance considers the error of the velocity as well as |
---|
| 881 | the error of the position - and ensure that both relative errors are within |
---|
| 882 | the "eps" maximum given. |
---|
| 883 | |
---|
| 884 | G4ChordFinder: |
---|
| 885 | Having found that the curve_length vs ABdist disrepancy has its basis in |
---|
| 886 | the imprecision of the integration: |
---|
| 887 | i) Modified the exception in this case to happen only for very large |
---|
| 888 | relative disrepancies ( 10 * eps ). |
---|
| 889 | ii) Undertaken a default corrective action in all other cases |
---|
| 890 | Note that this disrepancy only happens for very straight sections of track - |
---|
| 891 | ie step lengths much smaller than the curvature of the track. |

| 893 | July 1st, 1999 J. Apostolakis - field-01-00-06a |
---|
| 894 | |
---|
| 895 | In order to cope with the anomalous condition created by candidate fix |
---|
| 896 | in G4PropagatorInField, we ensure that the fraction_AE is always between |
---|
| 897 | 0 and 1.0. (giving it a default value of 0.5 whenever it is wrong). |

| 900 | June 29th, 1999 J. Apostolakis - field-01-00-06 |
---|
| 901 | |
---|
| 902 | I re-instated a check on whether the input distance along the curve between |
---|
| 903 | the two input curve points is truly greater than their linear distance. |
---|
| 904 | ( in G4ChordFinder::ApproxCurvePointV ) |
---|
| 905 | |
---|
| 906 | The condition that prints out a warning message has been altered to |

---|
| 920 | March 4th, 1999 J. Apostolakis - field-01-00-03 |
---|
| 921 | |

---|
| 925 | February 17th, 1999 J. Apostolakis - field-01-00-02 |

---|
| 927 | Moved G4PropagatorInField files to geometry/volumes. |

| 932 | February 12th, 1999 J. Apostolakis - field-spin1-works1 (act Feb17) |
---|
| 933 | |
---|
| 934 | A tag that contains the first version that worked with spin (in Peter G.'s |
---|
| 935 | directory). G4PropagateInSpin is still in this version. A small change |
---|
| 936 | in a branch of the header file was needed. |

---|
| 939 | February 10th, 1999 J. Apostolakis |
---|
| 940 | |
---|
| 941 | All the following changes are needed for energy integration also: |
---|
| 942 | |
---|
| 943 | G4ChordFinder now passes to the constructed driver the number of variables. |
---|
| 944 | Because of the need for the stepper to know about it in its Abstract interface |
---|
| 945 | |
---|
| 946 | -> Moved theNumberOfVariables from derived class G4MagErrorStepper |
---|
| 947 | to base class G4MagIntegratorStepper |
---|
| 948 | |
---|
| 949 | As a consequense the classes that derived from G4MagIntegratorStepper directly |
---|
| 950 | were changed: G4CashKarpRKF45, G4MagHelicalStepper, |
---|
| 951 | |
---|
| 952 | |
---|
| 953 | February 9th, 1999 J. Apostolakis |
---|
| 954 | |
---|
| 955 | Equation of Motion: |
---|
| 956 | G4MagEqRhs.hh Made SetChargeMomentumMass virtual, so that G4Mag_SpinEqRhs |
---|
| 957 | can initialise its constants too. |
---|

---|
| 967 | |
---|
| 968 | Moved G4PropagatorInField files to geometry/volumes. |

---|
| 994 | and clash of names in CashKarp::StepWithEstimate |
---|
| 995 | |
---|
| 996 | Added post-const to all Field classes for |

---|
| 1025 | ---------------------------------------------------------------------- |
---|
| 1026 | |
---|
| 1027 | 1) Added an assertion after each call to LocateGlobalPointAndSetup. |
---|
| 1028 | It checks that the located volume is equal to the current volume. |
---|
| 1029 | If this check fails, the Propagator does not know how to continue. |
---|
| 1030 | |
---|
| 1031 | 2) Added an argument to ComputeStep method of G4PropagatorInField. |
---|
| 1032 | The new volume argument is used to check the current volume during the step. |
---|
| 1033 | |
---|
| 1034 | 3) When G4Navigator's ComputeStep returned stepLength==stepRequested, this |
---|
| 1035 | used to be treated as a failure to intersect. This is incorrect. |
---|
| 1036 | |
---|
| 1037 | stepLength==stepRequested is an intersection, |
---|
| 1038 | so I am now treating it as such in each comparison (of 3). |
---|
| 1039 | Ignoring it causes problems, including volume being skipped. |
---|
| 1040 | --> but treating it as an intersection used to cause problems too ?? |

---|
| 1062 | Test of Helical stepping functionality added. |
