Hello,

I have a segmentation fault when running r3bsim_g4.C macro with a target geometry created by myself within the dev-branch of R3BRoot. I use the dev-branch to get the updated version of Startrack classes. I am running the simulation on GSI cluster with pre-installed ROOT6, FairSoft, FairRoot.
I also tried to re-create existing geometries, and the problem persist. Therefore I don't believe the problem is with the geometry definition. Below is the error message.

Any idea?
Thanks in advance,
Anna

Hello Anna,

I have tested the r3bsim_g4.C macro with re-created geometries, exactly with your software configuration on GSI linux cluster. I can not reproduce your segmentation fault.
Please post here the macro, which you use to create your own target geometry.

Just to be sure. What do you mean by "re-creating" other geometries? Can you post here the commands you have used for that?

Best regards,
Dima

Hi Dima,

Here is the file I use to create the target. I just added the function "CreateGeometry8".
By "re-create" I mean run the macro to generate anew a target that was already available in the macro, ie CreateGeometry# with # up to 7.
Just let me stress that I used the R3BRoot on dev-branch to get the updated startrack class.

Cheers,
Anna

Hi Anna,

I have found the problem. Here is the line from R3BTarget::ConstructGeometry() :

TGeoNode* main_vol = gGeoManager->GetTopVolume()->FindNode("TargetEnveloppe_0");


So you need to name the logical volume with H2 as "TargetEnveloppe" (inside of your ConstructGeometry8 function).

Best regards,
Dima
