Excitation-Energy Randomisation and Event Rate dropping

Created by: padsley

When I try to run NPTool using a histogram for excitation energy, I find that it tends to run very slowly, and gets slower in contrast to the very similar code for the random angle generation.

Has anyone else seen this happening with NPTOOL or another GEANT4 simulation? I'm presently running valgrind to try to work out if and when a memory leak is occurring but there's nothing obvious leaping out at me at the moment.

So... my query is: "Has anyone else seen this behaviour?" If you haven't ever tried using an Ex histogram input rather than one set value for Ex in the input file, could you try and let me know if it's got this same behaviour of the event rate dropping fairly quickly?

Thanks.
