Problems when using a cylindrical mesh in a fixed source simulation

Dear community,

I am running a fixed source simulation to tally the flux, which I want to use later for creating weight windows in a cylindrical mesh, but I did not manage to do it because:

I attach the pictures of the model I am using for this purpose.

  1. I ran the eigenvalue simulation and obtained the fission source (this worked well),

  2. I created a cylindrical mesh to tally the neutron flux and the simulation get stuck in a given particle number. Then, I cannot generate my weight window using this tally.

I saw that something similar was happening and was fixed in the mesh.cpp for a regular mesh, but maybe something similar is happening for the cylindrical mesh.

Your assistance would be supportful,

Best

Juan

Hi Juan,

I’d be interested in looking into this if you’re able to share the model!

Best,

Patrick
