Re: Question G4FissionEvent Segmentation Error (Odera Dim)
Date: 24 Oct, 2017
From: Odera Dim <Odera Dim>

Hi Experts,

I have an update to my previous post concerning the segmentation fault on the method G4fissionEvent. I was still in doubt that the segmentation fault I was having was from G4fissionEvent. So i decided to use the gdb debugging too to determine which method was causing the G4fissionEvent to fail. Surprisingly, gdb point to G4fission::G4SmpIsoDir (i.e the method that samples the momentum direction for the neutron particle generated).

I honestly find it hard to believe that this is the source of the issue as I believe some other geant4 users have called this function in some fashion. As I mentioned earlier, the behavior I am noticing only occurs after a number of thousands of events have been ran.

Any response will be appreciated. Thanks.
