|
|---|
| 453 | to enable the user to configure it with different accuracy parameters
|
|---|
| 454 | depending on energy, particle id, volume, or other track state.
|

| 457 | Jun 21st, 2003 J.Apostolakis - field-V05-01-03
|
|---|
| 458 | -----------------------------
|
|---|
| 459 | - Revised G4ChordFinder:
|
|---|
| 460 | * FindNextChord now provides next Step estimate (for accuracy in Integr.)
|
|---|
| 461 | * AdvanceChordLimited to use
|
|---|
| 462 | - above extra argument to FindNextChord
|
|---|
| 463 | - the next Step argument as initial-step suggested to Accurate Advance

| 519 | Nov 29th, 2002 J. Apostolakis - field-V04-01-04
|
|---|
| 520 | ---------------------------------
|
|---|
| 521 | Further fixes for unitialised variable - in other steppers:
|

|
|---|
| 528 | ---------------------------------
|
|---|
| 529 | Further fixes for unitialised variables:
|
|---|
| 530 |
|
|---|
| 531 | * G4MagIntegratorStepper
|
|---|
| 532 | - Created instance variables for number of Integration, State variables
|
|---|
| 533 |
|
|---|
| 534 | * G4MagErrorStepper
|
|---|
| 535 | - Utilise number of State variables to initialise full state of Output.

| 538 | - Initialise the values of dydx that we do not update.
|
|---|
| 539 |
|
|---|

|
|---|
| 541 | if undefined values are used in variables that he/she expects to
|
|---|
| 542 | have integrated.
|
|---|
| 543 | BUT the fix assists us to find truly undefined values elsewhere
|
|---|
| 544 | -- if they exist -- using valgrind.
|
|---|
| 545 |
|
|---|
| 546 | Nov 9th, 2002 J. Apostolakis - field-V04-01-02
|
|---|
| 547 | ---------------------------------
|
|---|
| 548 | Fixes to address use of uninitialised variable in seting values of FieldTrack
|
|---|
| 549 | (this was done by design, but was neither ideal or always well-behaved.)
|
|---|
| 550 | Changed:
|
|---|
| 551 |
|
|---|
| 552 | * G4MagIntegratorDriver

| 558 | - Copy the initial time to intermediate and output C-vectors,
|
|---|
| 559 | in order to provide a zero-eth estimate value.
|
|---|
| 560 | Note1: Should clean-up this fix, making it similar to Driver (above)
|
|---|
| 561 | Note2: Should *not* be used for time varying field unless created
|
|---|
| 562 | with at least 8 integration variables
|
|---|
| 563 | ---------------------------------
|
|---|
| 564 | G4ChordFinder.cc

|
|---|
| 568 | and new print method for 'debugging'
|

|
|---|
| 583 | G4PropagatorInField.
|
|---|

| 711 | G4FieldManager
|
|---|
| 712 | - Added fFieldChangesEnergy data member and get/set methods

| 738 | Nov 9th, 2001 J. Apostolakis - field-V03-02-03
|
|---|
| 739 | -----------------------------
|
|---|
| 740 | Motivated by the use case of an Electric Field,
|
|---|
| 741 | - in order to achieve reasonable accuracy in time integration,
|
|---|
| 742 | - and to enable fields that vary with the global time)
|
|---|
| 743 | we (John Ap. and V. Grichine) changed the following:
|
|---|
| 744 |
|
|---|
| 745 | - Modified G4Field to allow the time in the GetFieldValue method
|
|---|
| 746 | - as 4th component of the "position" array.
|
|---|
| 747 |
|
|---|
| 748 | - Modified EquationOfMotion to provide the time to the GetFieldValue method
|
|---|
| 749 | of G4Field
|
|---|
| 750 | * as the 4th component of a position / time 4-array
|
|---|
| 751 | * in place of only position as a 3-arry
|
|---|
| 752 |
|
|---|
| 753 | - Added the global time as variable to be integrated over in the
|
|---|
| 754 | case of an Electric Field
|
|---|
| 755 |
|
|---|
| 756 | Support for these modifications is required in G4Transportation.
|
|---|
| 757 |
|
|---|
| 758 | (Better support will require either
|
|---|
| 759 | - a modification in G4FieldTrack to indicate whether the time has been
|
|---|
| 760 | integrated or not.
|
|---|
| 761 | - or additionally making the time calculation a property of G4FieldTrack,
|
|---|
| 762 | bring in code to do it in from G4Transportation.)
|
|---|
| 763 |
|
|---|
| 764 |
|

| 765 | Nov 8th, 2001 J. Apostolakis - field-V03-02-02
|
|---|
| 766 | ------------------------
|
|---|
| 767 | - Introduced several changes in G4MagIntegratorDriver.
|
|---|
| 768 |
|
|---|
| 769 | It now respects its minimum driver step size in AccurateAdvance.
|
|---|
| 770 | * whereas before it did not.
|
|---|
| 771 |
|
|---|
| 772 | Modified maximum number of steps, lowering by factor of 10.
|
|---|
| 773 | -> it should reduce the time spent integrating low energy particles,
|
|---|
| 774 | in some cases where it is unneccessary.
|
|---|
| 775 |
|
|---|
| 776 | Protected printing of (nearly?) all warnings with a G4DEBUG_FIELD #ifdef.
|
|---|
| 777 |

|---|
| 788 | Aug 16th, 2001 J. Apostolakis
|
|---|
| 789 | ------------------------------
|
|---|
| 790 | G4ChordFinder:
|
|---|
| 791 | Added method to erase/reset the state of the StepEstimate.
|
|---|
| 792 | This is unwanted internal state that was carried between tracks and
|
|---|
| 793 | events as a side effect.
|
|---|
| 794 |
|
|---|
| 795 | Calling this at the start of each track, it is now possible to
|
|---|
| 796 | eliminate a non-repeatability that was possible due to this.
|
|---|
| 797 | ( It has been observed in particular in vaccuum. )
|

| 824 | Test outputs saved (on Linux).
|
|---|
| 825 |
|
|---|
| 826 | - Fixed src/G4UniformElectricField.cc to set correct field components
|
|---|
| 827 | (compatible with Equation of Motion
|
|---|
| 828 | G4EqMagElectricField )
|
|---|
| 829 |
|
|---|
| 830 | - Tidied G4FieldTrack
|
|---|
| 831 | * deleted obsolete methods Set/Get MomentumModulus() and its data member.
|
|---|
| 832 | * in constructor to set the value of the spin to (0.0, 0.0, 0.0)
|
|---|
| 833 | if pSpin is null. (It was undefined.)
|
|---|
| 834 |

|
|---|
| 855 | ------------------------------
|
|---|
| 856 | - Tagging the modification of several classes to integrate in momentum*c_light
|
|---|
| 857 | instead of velocity.
|

|
|---|
| 992 |
|
|---|
| 993 | These fixes and those in field-01-00-06 and field-01-00-06a all come
|
|---|
| 994 | from the need to cope with the imprecision of the integration, and its
|
|---|
| 995 | interaction with paths that are rather straight.
|
|---|
| 996 |
|
|---|
| 997 | G4MagIntegrationDriver:
|
|---|
| 998 | i) AccurateAdvance now that the chord distance is smaller than the curve len-
|
|---|
| 999 | gth (times 1+epsilon).
|
|---|
| 1000 |
|
|---|
| 1001 | ii) OneGoodStep and QuickAdvance considers the error of the velocity as well as
|
|---|
| 1002 | the error of the position - and ensure that both relative errors are within
|
|---|
| 1003 | the "eps" maximum given.
|
|---|
| 1004 |
|
|---|
| 1005 | G4ChordFinder:
|
|---|
| 1006 | Having found that the curve_length vs ABdist disrepancy has its basis in
|
|---|
| 1007 | the imprecision of the integration:
|
|---|
| 1008 | i) Modified the exception in this case to happen only for very large
|
|---|
| 1009 | relative disrepancies ( 10 * eps ).
|
|---|
| 1010 | ii) Undertaken a default corrective action in all other cases
|
|---|
| 1011 | Note that this disrepancy only happens for very straight sections of track -
|
|---|
| 1012 | ie step lengths much smaller than the curvature of the track.

| 1016 | In order to cope with the anomalous condition created by candidate fix
|
|---|
| 1017 | in G4PropagatorInField, we ensure that the fraction_AE is always between
|
|---|
| 1018 | 0 and 1.0. (giving it a default value of 0.5 whenever it is wrong).

|
|---|
| 1063 |
|
|---|
| 1064 | G4ChordFinder now passes to the constructed driver the number of variables.
|
|---|
| 1065 | Because of the need for the stepper to know about it in its Abstract interface
|
|---|
| 1066 |
|
|---|
| 1067 | -> Moved theNumberOfVariables from derived class G4MagErrorStepper
|
|---|
| 1068 | to base class G4MagIntegratorStepper
|
|---|
| 1069 |
|
|---|
| 1070 | As a consequense the classes that derived from G4MagIntegratorStepper directly

|

| 1147 |
|
|---|
| 1148 | 1) Added an assertion after each call to LocateGlobalPointAndSetup.
|
|---|
| 1149 | It checks that the located volume is equal to the current volume.
|
|---|
| 1150 | If this check fails, the Propagator does not know how to continue.
|
|---|
| 1151 |
|
|---|
| 1152 | 2) Added an argument to ComputeStep method of G4PropagatorInField.
|
|---|
| 1153 | The new volume argument is used to check the current volume during the step.
|
|---|
| 1154 |
|
|---|
| 1155 | 3) When G4Navigator's ComputeStep returned stepLength==stepRequested, this
|
|---|
| 1156 | used to be treated as a failure to intersect. This is incorrect.
|
|---|
| 1157 |
|
|---|
| 1158 | stepLength==stepRequested is an intersection,
|
|---|
| 1159 | so I am now treating it as such in each comparison (of 3).
|
|---|
| 1160 | Ignoring it causes problems, including volume being skipped.
|
|---|
| 1161 | --> but treating it as an intersection used to cause problems too ??
