Thank you for kind reply sir and sorry for the late response
I am already used “/process/msc” UI commands in my program. But the result almost the same for proton simulation. (for Step limit type, Range factor, Geom Factor, dRoverRange, Final Range)
/process/eLoss/StepFunction 0.1 0.02 mm
My problem: The small field proton simulation the PDD & total Fluence results showing differences in dose entrance. Before I am used Geant4 10.02.p02 and G4EmStandardPhysics_option4, I got a good result for a small field. But the new version of Geant4 10.04.p02 and G4EmStandardPhysics_option4, shown the wrong result for a small field. So, how to slow this problem? please help me... thank you...
I am attached PDF file for Geant4 10.04.p02 & option4 results. I mentioned the error part of the result.
