Re: Sad Quitting without error message when creating multiple Sensitive Detector volumes (Blair Smith)

Drat! I found the problem, I was using the wrong logical volume from a prior version of my code that I no longer have defined.

But I have another question that I might post as a separate thread, the question is, what will happen if I have say two volumes set as SD and one is a daughter volume of the other, say "logicModule" is a daughter of "logicHouse".

When a particle scatters in a physical placement of a logicModule what will happen? Will ProcessHit() get called for both of these sensitive volumes, or will the lower level daughter logicModule only get actuated?

I ask because I would like to avoid setting up seperate hit collections and the behaviour I want is for each hit to activate ProcessHits() only once (and preferrably for the deepest embedded of the possibly nested sensitive volumes).

Cheers,

Blair
