*** G4Exception : Transport-001-ExcessSteps
|
||||
issued by : G4Transportation::AlongStepDoIt
|
||||
Transportation is killing track that is looping or stuck.
|
||||
Track is proton and has 2.99993 MeV energy ( pre-Step = 2.99993 )
|
||||
momentum = (-1.22735,2.16099,75.0488) mag= 75.0899
|
||||
position = (-0.0779194,0.017239,250) is in volume 'World', its material is 'Vacuum' with density = 1e-25 g/cm^3
|
||||
Total number of Steps by this track: 9122
|
||||
Length of this step = 2553.49 mm
|
||||
Number of propagation trials = 1 ( vs maximum = 10 for 'important' particles )
|
||||
( Number of *calls* of Transport/AlongStepDoIt = 291906 )
|
||||
=============== Recommendations / advice ====================
|
||||
Recommendations to address this issue (Transport-001-ExcessSteps)
|
||||
This warning is controlled by the SetThresholdWarningEnergy method of G4Transportation.
|
||||
Current value of 'warning' threshold= 1 MeV
|
||||
- If 'unimportant' particles (with energy low enough not to matter in your application, then increase its value.
|
||||
- If particles of high-enough energy to be important are being killed, you can
|
||||
a) Increase the trial steps using the method SetThresholdTrials(). Particles above the 'important' threshold
|
||||
will be given this many 'chances'. The default value was 10, and the current value is 10
|
||||
b) Increase the energy which you consider 'important' (above this they are killed only after extra trials), using the method SetThresholdImportantEnergy()
|
||||
Note: this can incur a potentially high cost in extra simulation time if more tracks require very large number of integration steps .
|
||||
c) investigate alternative integration methods
|
||||
e.g. Helical methods for uniform or almost uniform fields or else higher order RK methods such as DormandPrince78
