|---|
| 21 | ----------------------------- |
|---|
| 22 | - G4Nystrom: Corrected interface method getField: array now has explicit dimension[4] |

|---|
| 421 | ----------------------------- |
|---|
| 422 | - G4FieldManager: |
|---|
| 423 | o Revised into 'slightly' abstract class with one (new) virtual method: |
|---|
| 424 | ConfigureForTrack( const G4Track *) |
|---|
| 425 | to enable the user to configure it with different accuracy parameters |
|---|
| 426 | depending on energy, particle id, volume, or other track state. |

|---|
| 487 | --------------------------- |
|---|

|---|
| 500 | --------------------------------- |
|---|
| 501 | Further fixes for unitialised variables: |
|---|
| 502 | |
|---|
| 503 | * G4MagIntegratorStepper |
|---|
| 504 | - Created instance variables for number of Integration, State variables |
|---|
| 505 | |

| 510 | - Initialise the values of dydx that we do not update. |
|---|
| 511 | |
|---|
| 512 | Note: Undoing these changes and the ones below would enable the user to see |
|---|
| 513 | if undefined values are used in variables that he/she expects to |
|---|
| 514 | have integrated. |
|---|
| 515 | BUT the fix assists us to find truly undefined values elsewhere |
|---|
| 516 | -- if they exist -- using valgrind. |
|---|
| 517 | |
|---|
| 518 | Nov 9th, 2002 J. Apostolakis - field-V04-01-02 |
|---|
| 519 | --------------------------------- |
|---|
| 520 | Fixes to address use of uninitialised variable in seting values of FieldTrack |
|---|
| 521 | (this was done by design, but was neither ideal or always well-behaved.) |
|---|

|---|
| 530 | - Copy the initial time to intermediate and output C-vectors, |
|---|
| 531 | in order to provide a zero-eth estimate value. |
|---|
| 532 | Note1: Should clean-up this fix, making it similar to Driver (above) |
|---|
| 533 | Note2: Should *not* be used for time varying field unless created |
|---|
| 534 | with at least 8 integration variables |
|---|
| 535 | --------------------------------- |
|---|
| 536 | G4ChordFinder.cc |

|---|
| 554 | PropagatorInField in order to be ready for its full use in |
|---|
| 555 | G4PropagatorInField. |
|---|
| 556 | (A key problem at end-July was this non-preparedness of the unit tests.) |
|---|
| 557 | |
|---|

| 698 | Nov 21st, 2001 G. Cosmo - field-V03-02-05 |
|---|
| 699 | ------------------------ |
|---|
| 700 | - Protected verbose warnings with G4FIELD_DEBUG flag in G4ChordFinder.cc |
|---|
| 701 | (V.Grichine). |
|---|
| 702 | - Replaced G4DEBUG with G4DEBUG_FIELD in G4MagIntegratorDriver.cc. |
|---|
| 703 | - Updates to unit test field02. |
|---|
| 704 | |
|---|
| 705 | Nov 13th, 2001 G. Cosmo - field-V03-02-04 |
|---|
| 706 | ------------------------ |
|---|
| 707 | - Removed warnings on gcc-2.95.2. |
|---|
| 708 | - Included unit tests field01, field02, field03. |
|---|
| 709 | |
|---|
| 710 | Nov 9th, 2001 J. Apostolakis - field-V03-02-03 |
|---|
| 711 | ----------------------------- |
|---|
| 712 | Motivated by the use case of an Electric Field, |
|---|
| 713 | - in order to achieve reasonable accuracy in time integration, |
|---|
| 714 | - and to enable fields that vary with the global time) |
|---|
| 715 | we (John Ap. and V. Grichine) changed the following: |
|---|
| 716 | |
|---|
| 717 | - Modified G4Field to allow the time in the GetFieldValue method |
|---|
| 718 | - as 4th component of the "position" array. |
|---|
| 719 | |
|---|
| 720 | - Modified EquationOfMotion to provide the time to the GetFieldValue method |
|---|
| 721 | of G4Field |
|---|
| 722 | * as the 4th component of a position / time 4-array |
|---|
| 723 | * in place of only position as a 3-arry |
|---|
| 724 | |
|---|
| 725 | - Added the global time as variable to be integrated over in the |
|---|
| 726 | case of an Electric Field |
|---|
| 727 | |
|---|
| 728 | Support for these modifications is required in G4Transportation. |
|---|
| 729 | |
|---|
| 730 | (Better support will require either |
|---|
| 731 | - a modification in G4FieldTrack to indicate whether the time has been |
|---|
| 732 | integrated or not. |
|---|
| 733 | - or additionally making the time calculation a property of G4FieldTrack, |
|---|
| 734 | bring in code to do it in from G4Transportation.) |
|---|
| 735 | |
|---|
| 736 | |
|---|
| 737 | Nov 8th, 2001 J. Apostolakis - field-V03-02-02 |
|---|
| 738 | ------------------------ |
|---|
| 739 | - Introduced several changes in G4MagIntegratorDriver. |
|---|
| 740 | |
|---|
| 741 | It now respects its minimum driver step size in AccurateAdvance. |
|---|
| 742 | * whereas before it did not. |
|---|
| 743 | |
|---|
| 744 | Modified maximum number of steps, lowering by factor of 10. |
|---|
| 745 | -> it should reduce the time spent integrating low energy particles, |
|---|
| 746 | in some cases where it is unneccessary. |
|---|
| 747 | |
|---|
| 748 | Protected printing of (nearly?) all warnings with a G4DEBUG_FIELD #ifdef. |
|---|
| 749 | |
|---|
| 750 | |
|---|
| 751 | Nov 05th, 2001 G. Cosmo - field-V03-02-01 |

|---|
| 756 | ------------------------------ |
|---|
| 757 | Tagged last change. |
|---|
| 758 | This tag is utilised in transport-V03-02-01 (which requires it). |
|---|
| 759 | |
|---|
| 760 | Aug 16th, 2001 J. Apostolakis |
|---|
| 761 | ------------------------------ |
|---|
| 762 | G4ChordFinder: |
|---|
| 763 | Added method to erase/reset the state of the StepEstimate. |
|---|
| 764 | This is unwanted internal state that was carried between tracks and |
|---|
| 765 | events as a side effect. |
|---|
| 766 | |
|---|
| 767 | Calling this at the start of each track, it is now possible to |
|---|
| 768 | eliminate a non-repeatability that was possible due to this. |
|---|
| 769 | ( It has been observed in particular in vaccuum. ) |
|---|
| 770 | |

|---|
| 778 | parameters. |
|---|
| 779 | |
|---|
| 780 | - Updated testPropagateSpin (it now compiles), |
|---|
| 781 | and some outputs of testPropagateMagField (1 to 5) |
|---|
| 782 | |
|---|
| 783 | |

|---|
| 785 | ----------------------------- |
|---|
| 786 | - Updated G4Mag_SpinEqRhs.hh and G4Mag_SpinEqRhs.cc for correction |
|---|
| 787 | to spin tracking. |
|---|
| 788 | |
|---|
| 789 | Apr 04th, 2001 G. Cosmo - field-V03-00-05 |
|---|
| 790 | ------------------------ |
|---|
| 791 | - G4FieldTrack.icc: fixed pedantic warnings on Linux-g++. |
|---|
| 792 | |
|---|
| 793 | Mar 23rd, 2001 J. Apostolakis - field-V03-00-04 |
|---|
| 794 | ------------------------------ |
|---|
| 795 | - Electric Field unit test now works: test runs until completion. |
|---|
| 796 | Test outputs saved (on Linux). |
|---|
| 797 | |
|---|
| 798 | - Fixed src/G4UniformElectricField.cc to set correct field components |
|---|
| 799 | (compatible with Equation of Motion |
|---|
| 800 | G4EqMagElectricField ) |
|---|
| 801 | |
|---|
| 802 | - Tidied G4FieldTrack |
|---|
| 803 | * deleted obsolete methods Set/Get MomentumModulus() and its data member. |
|---|
| 804 | * in constructor to set the value of the spin to (0.0, 0.0, 0.0) |
|---|
| 805 | if pSpin is null. (It was undefined.) |
|---|
| 806 | |
|---|
| 807 | Mar 23rd, 2001 J. Apostolakis - field-V03-00-03 |
|---|
| 808 | ------------------------------ |
|---|
| 809 | - Fixed (hacked) CashKarp to work using Auxiliary Stepper. |
|---|
| 810 | |
|---|
| 811 | - Modified G4MagIntegratorStepper |
|---|
| 812 | to use pointer to G4EquationOfMotion |
|---|
| 813 | instead of G4Mag_EqRhs |
|---|
| 814 | |
|---|
| 815 | - Design iteration appears neccessary |
|---|
| 816 | |
|---|
| 817 | Mar 23rd, 2001 J. Apostolakis - field-V03-00-02 |
|---|
| 818 | ------------------------------ |
|---|
| 819 | - Fixed G4MagHelicalStepper::AdvanceHelix for momentum, allowing |
|---|
| 820 | the possibility of (correct) use of all Helical Steppers. |
|---|
| 821 | |
|---|
| 822 | - test/testProElectroMagField.cc updated for momentum. |
|---|
| 823 | (Not yet updated: Spin tests) |
|---|
| 824 | |
|---|
| 825 | |
|---|
| 826 | Mar 19th, 2001 J. Apostolakis - field-V03-00-01 |
|---|
| 827 | ------------------------------ |
|---|
| 828 | - Tagging the modification of several classes to integrate in momentum*c_light |
|---|
| 829 | instead of velocity. |
|---|
| 830 | Reason for change: Velocity integration can result in superluminar |
|---|
| 831 | velocities, due to arithmetic inaccuracies. |
|---|
| 832 | Classes modified: |
|---|
| 833 | G4FieldTrack, (Changed components 3,4,5 of SixVector to Momentum, |
|---|
| 834 | G4Mag_EqRhs, G4Mag_UsualEqRhs, G4EqMagElectricField |
|---|
| 835 | |

|---|
| 841 | Changed components 3,4,5 of SixVector to Momentum, |
|---|
| 842 | Modified constructor |
|---|
| 843 | Added energy calculation to "LoadFromArray" method |
|---|
| 844 | GetEnergy method is now implemented. |
|---|

|---|
| 846 | |
|---|
| 847 | G4ChordFinder |
|---|
| 848 | Renamed old-method names of Field Track to new ones. |

|---|
| 851 | ------------------------- |
|---|
| 852 | |
|---|
| 853 | - Minor fix to G4MagneticField.hh: added explicit call to G4Field() in |
|---|
| 854 | copy constructor. Fixes report #205. |
|---|

|---|
| 856 | Nov 20th, 2000 G. Cosmo - field-V02-00-02 |
|---|
| 857 | |
|---|
| 858 | - Fixes to remove warnings from "-Wall -ansi -pedantic" g++ compiler options: |
|---|
| 859 | o commented out variables declared and not used. |
|---|
| 860 | o fixed declaration of variables used before being initialised. |
|---|
| 861 | o fixed order of initialisation of member data in constructors. |
|---|

|---|
| 863 | |
|---|
| 864 | Nov 9th, 2000 G. Cosmo - field-V02-00-01 |
|---|
| 865 | |

|---|
| 867 | in CreateChordFinder(G4MagneticField*) method. |
|---|
| 868 | |
|---|
| 869 | Nov 1st, 2000 G. Cosmo - field-V02-00-00 |
|---|
| 870 | |
|---|
| 871 | - QA code revision and cleanup (+fixes from CodeWizard filtering): |
|---|
| 872 | o Added (private) declarations of copy constructor and assignment operator |
|---|
| 873 | where needed. |
|---|
| 874 | o Added "const" qualifier to accessor methods, wherever needed. |
|---|
| 875 | o Added equality check on operator= where needed. |
|---|
| 876 | o Made destructor "virtual" for classes having virtual methods, |
|---|
| 877 | wherever missing. |
|---|
| 878 | o Changed virtual functions to non-inline wherever's the case. |
|---|
| 879 | o Changed return value to be "const" pointer to functions: |

|---|
| 887 | Jun 2nd, 2000 J. Apostolakis |
|---|
| 888 | - G4FieldManager[.hh.icc] |
|---|
| 889 | o Added DeltaIntersection and DeltaOneStep to FieldManager: added |
|---|
| 890 | Get/Set methods and SetAccuraciesWithDeltaOneStep(). |
|---|
| 891 | |
|---|
| 892 | May 31st, 2000 J. Apostolakis - field-V01-01-03 |
|---|
| 893 | |
|---|
| 894 | include/G4FieldManager.hh,icc |
|---|
| 895 | o Moved Delta Intersection and Delta One Step to FieldManager |
|---|
| 896 | (from Propagator in Field), to allow them to differ over the detector. |
|---|
| 897 | |
|---|
| 898 | May 11th, 2000 J. Apostolakis - field-V01-01-02 |
|---|
| 899 | |
|---|
| 900 | - G4ChordFinder[.hh.cc] |
|---|
| 901 | o Modified method for finding new trial step. |
|---|
| 902 | New method assumes a quadratic relationship between step-length and d_chord: |
|---|
| 903 | d_chord proportional to step-lenght ^ 2 |
|---|
| 904 | o Added two small refinement in order to avoid unneccesary extra step due to |
|---|
| 905 | small numerical inaccuracies in estimation: |
|---|
| 906 | FindNextChord |
|---|
| 907 | to first step use (1-0.001) * last-step-estimate |
|---|
| 908 | New Step: |
|---|
| 909 | to subsequent step use trial_step = 0.98 * estimate |
|---|

|---|
| 911 | May 10th, 2000 G. Cosmo |
|---|
| 912 | |

|---|
| 922 | Deleted error message from StepNoErr, as it is used in Stepper. |
|---|
| 923 | |
|---|
| 924 | - G4MagIntegratorDriver: |
|---|
| 925 | Changed the condition for the debug output (~cosmetic) |

|---|
| 928 | April 27th, 2000 G. Cosmo |
|---|
| 929 | |
|---|
| 930 | - Reorganised comments for the Software Reference Manual. |
|---|
| 931 | - Moved inlined definition to .icc files, where needed. |
|---|

| 934 | April 13th, 2000 J. Apostolakis - field-V01-01-00 |
|---|
| 935 | |
|---|
| 936 | - Modified signature to function DumbStepper() in classes: |
|---|
| 937 | G4HelixExplicitEuler, G4HelixHeum, G4HelixImplicitEuler, |
|---|
| 938 | G4HelixSimpleRunge and G4MagHelicalStepper. |
|---|
| 939 | - Modified signature and implementation of function MagFieldEvaluate() |
|---|
| 940 | in G4MagHelicalStepper, to use Field (as ThreeVector) in place of dydx. |
|---|
| 941 | - Made Richardson extrapolation optional (it is unclear if |
|---|
| 942 | it offers benefit) in G4MagHelicalStepper. |
|---|
| 943 | - Updated unit test testPropagateMagField and reference output. |
|---|
| 944 | - G4LineSection: fixes to prevent divisions by 0. and sqrt(<0) |
|---|
| 945 | (V.Grichine). |
|---|
| 946 | |

| 949 | Syncronized versioning of files with HEAD after ISO-C++ migration |
|---|
| 950 | (essentially CVS header changes). |
|---|
| 951 | |
|---|
| 952 | December 7th, 1999 J. Apostolakis - field-V00-01-01a |
|---|
| 953 | |
|---|
| 954 | For negative or very small curve lengths (h) we suppress writing an error |
|---|
| 955 | (about the distance of endpoints being further than the curve length), |
|---|
| 956 | as it is meaningless. |
|---|

| 963 | July 6th, 1999 J. Apostolakis - field-01-00-07 |
|---|
| 964 | |
|---|
| 965 | These fixes and those in field-01-00-06 and field-01-00-06a all come |
|---|
| 966 | from the need to cope with the imprecision of the integration, and its |
|---|
| 967 | interaction with paths that are rather straight. |
|---|
| 968 | |
|---|
| 969 | G4MagIntegrationDriver: |
|---|
| 970 | i) AccurateAdvance now that the chord distance is smaller than the curve len- |
|---|
| 971 | gth (times 1+epsilon). |
|---|
| 972 | |
|---|
| 973 | ii) OneGoodStep and QuickAdvance considers the error of the velocity as well as |
|---|
| 974 | the error of the position - and ensure that both relative errors are within |
|---|
| 975 | the "eps" maximum given. |
|---|
| 976 | |
|---|
| 977 | G4ChordFinder: |
|---|
| 978 | Having found that the curve_length vs ABdist disrepancy has its basis in |
|---|
| 979 | the imprecision of the integration: |
|---|
| 980 | i) Modified the exception in this case to happen only for very large |
|---|
| 981 | relative disrepancies ( 10 * eps ). |
|---|
| 982 | ii) Undertaken a default corrective action in all other cases |
|---|
| 983 | Note that this disrepancy only happens for very straight sections of track - |
|---|
| 984 | ie step lengths much smaller than the curvature of the track. |

| 985 | |
|---|
| 986 | July 1st, 1999 J. Apostolakis - field-01-00-06a |
|---|
| 987 | |
|---|
| 988 | In order to cope with the anomalous condition created by candidate fix |
|---|
| 989 | in G4PropagatorInField, we ensure that the fraction_AE is always between |
|---|
| 990 | 0 and 1.0. (giving it a default value of 0.5 whenever it is wrong). |

| 993 | June 29th, 1999 J. Apostolakis - field-01-00-06 |
|---|
| 994 | |
|---|
| 995 | I re-instated a check on whether the input distance along the curve between |
|---|
| 996 | the two input curve points is truly greater than their linear distance. |
|---|
| 997 | ( in G4ChordFinder::ApproxCurvePointV ) |
|---|
| 998 | |
|---|
| 999 | The condition that prints out a warning message has been altered to |
|---|
| 1000 | take into account the case of a very small final interval. |

|---|
| 1004 | |
|---|
| 1005 | The condition that prints out a warning message was changed to delete |

| 1013 | March 4th, 1999 J. Apostolakis - field-01-00-03 |
|---|
| 1014 | |
|---|
| 1015 | Corrected delete statement of arrays to use 'delete[]' instead of simple delete |
|---|
| 1016 | in destructors of 2 steppers (G4CashKarpRKF45, G4SimpleHeum) |

| 1018 | February 17th, 1999 J. Apostolakis - field-01-00-02 |
|---|
| 1019 | |
|---|
| 1020 | Moved G4PropagatorInField files to geometry/volumes. |
|---|
| 1021 | Updated GNUmakefile not to depend on geometry/volumes anymore. |
|---|
| 1022 | -> the known circular dependency is removed |
|---|

| 1025 | February 12th, 1999 J. Apostolakis - field-spin1-works1 (act Feb17) |
|---|
| 1026 | |
|---|
| 1027 | A tag that contains the first version that worked with spin (in Peter G.'s |
|---|
| 1028 | directory). G4PropagateInSpin is still in this version. A small change |
|---|
| 1029 | in a branch of the header file was needed. |

|---|
| 1033 | |
|---|
| 1034 | All the following changes are needed for energy integration also: |
|---|
| 1035 | |
|---|
| 1036 | G4ChordFinder now passes to the constructed driver the number of variables. |
|---|
| 1037 | Because of the need for the stepper to know about it in its Abstract interface |
|---|
| 1038 | |
|---|
| 1039 | -> Moved theNumberOfVariables from derived class G4MagErrorStepper |
|---|
| 1040 | to base class G4MagIntegratorStepper |
|---|
| 1041 | |
|---|
| 1042 | As a consequense the classes that derived from G4MagIntegratorStepper directly |
|---|
| 1043 | were changed: G4CashKarpRKF45, G4MagHelicalStepper, |
|---|
| 1044 | |
|---|
| 1045 | |
|---|
| 1046 | February 9th, 1999 J. Apostolakis |
|---|
| 1047 | |
|---|
| 1048 | Equation of Motion: |
|---|
| 1049 | G4MagEqRhs.hh Made SetChargeMomentumMass virtual, so that G4Mag_SpinEqRhs |
|---|
| 1050 | can initialise its constants too. |

| 1061 | Moved G4PropagatorInField files to geometry/volumes. |
|---|
| 1062 | Updated GNUmakefile not to depend on geometry/volumes anymore. |

| 1114 | Modified Files: |

| 1115 | include/G4PropagatorInField.hh |
|---|
| 1116 | src/G4PropagatorInField.cc |

|---|
| 1120 | 1) Added an assertion after each call to LocateGlobalPointAndSetup. |
|---|
| 1121 | It checks that the located volume is equal to the current volume. |
|---|
| 1122 | If this check fails, the Propagator does not know how to continue. |
|---|
| 1123 | |
|---|
| 1124 | 2) Added an argument to ComputeStep method of G4PropagatorInField. |
|---|
| 1125 | The new volume argument is used to check the current volume during the step. |
|---|
| 1126 | |
|---|
| 1127 | 3) When G4Navigator's ComputeStep returned stepLength==stepRequested, this |
|---|
| 1128 | used to be treated as a failure to intersect. This is incorrect. |
|---|
| 1129 | |
|---|
| 1130 | stepLength==stepRequested is an intersection, |
|---|
| 1131 | so I am now treating it as such in each comparison (of 3). |
|---|
| 1132 | Ignoring it causes problems, including volume being skipped. |
|---|
| 1133 | --> but treating it as an intersection used to cause problems too ?? |

|---|
| 1152 | made RightHandSide virtual (this will be reversed very soon) |
|---|
| 1153 | |
|---|
| 1154 | testPropagateMagField.cc |
|---|
| 1155 | Test of Helical stepping functionality added. |
|---|
| 1156 | |
|---|
| 1157 | Added Files for new Helical RK steppers, deriving from G4MagErrorStepper: |
|---|
| 1158 | G4HelixExplicitEuler.cc ( and .hh ) |
|---|
| 1159 | G4HelixHeum.cc |
|---|
| 1160 | G4HelixImplicitEuler.cc |
|---|
| 1161 | G4HelixSimpleRunge.cc |
