The primary origin of the generated particles are not located at the expected position

A priori the size=(0,0,0)mm just defines a ponctual primary origin. I tried with size="(100,0,0)mm and the same problem appears.

Ok, not sure what the problem is now, but from what I see, the generator is doing as expected. You would need to get some statistics and plot the primary origin X-Y distribution to see that it is in a circle of radius 10cm.

Perhaps it is an issue related with the visualisation of the geometry and the hits.

Sensitive volume not working for saving specific events

I think the problem is not with the simulation, but with the visualization tool… Looking at the positions of the hits, it seems that the simulation is working correctly (good news). But the restGeant4_ViewEvent visualization tool I think is not. It is showing the event and the geometry in different scales, or something like that, and so, it looks like the event is out of the volume when, in reality, it is not. Well, I lost a lot of time on this, but at least nothing important…

I advice you to have a look to PrintEvent() to see if things make sense there.
