|
// Simple placeholder for user Step limitations
|
|
// In order to activate these limitations, users need to register
|
|
// their "special" processes to each particle they want.
|
|
// Sample processes below can be found under processes/transportation
|
|
// MaxAllowedStep : UserStepLimit
|
|
// other limitation : UserSpecialCuts
|
|
// In addition, users can add their own Step limitations by creating
|
|
// new class derived from G4UserLimits. In these case, fType member
|
|
// is supposed to be used to identify class.
