I use GEANT452 patch 01, 02 When I simulate nuclear reaction with cascade interface model, if the thickness of the sample is too large, the program enters in an infinite loop. For instabnce P+(754MeV) W nuclear reaction in 0.1 mm thicness target is ok But in 1mm or 1 cm thickness it goes into a loop.
Aatos has looked into this, and assures me he has fixed in in his last tag. The changes will go into the 6.0 release. Many greetings, Hans-Peter.
