Re: Microscopic Cross Sections of selected isotopes

Hi Anna, thanks for your reply. About the material card, yes, there's a "mat" missing in my previous post, but not in the code. It's just a typo I made here. The input that I posted here is a simplified version of the actual one; in reality I have 4 different material cards, therefore I will use du ...

Microscopic Cross Sections of selected isotopes

Hi all, My goal is to determine the 2-group integrated microscopic cross sections for some isotopes in my system. My system is simplified; it's just a cubic cell filled with a mixture of my isotopes. The relevant parts of code for geometry and material are as follows (don't focus on the compositions...

Re: How to get external source?

Hi again, I solved the problem. There was some problem with the volume of one of the materials. My current problem is about the dose calculation with the GVR getting stuck after the message "Starting external source simulation". My geometry consists in a simple hollow cylinder inside which I place m...

Re: How to get external source?

Hi Jakko, I am running a photon shielding calculation (with variance reduction) where the spent fuel is used as the photon source. In simplified terms, my spent fuel is arranged in a cylinder surrounded by a lead cylindrical shell. I want to measure my quantities of interest on the outside of a lead...
