Hello group!

I am trying to run OpenMC depletion module on my Mac. The case is very simple, but I got the following error:

The XS file does exist in my XS library, and it works well when I only run the particle transport calculation (model.run()). Does anyone have any idea? Many thanks.

I’ve attached my input file.

hi @wxinyan ;

I’ve tried your input file, with some modifications to allow it to work on my machine (Debian), and it seems to work well after these modifications:

  1. I work with notebooks with OpenMC0.15, so your python file was converted into a notebook with 3 code cells (see attached file). Besides that, some instances need update with OpenMC0.15, but for now you get only warnings and it works!
    Fe_model.ipynb (14.8 KB)
  2. I placed the chain file directly on the working directory to avoid issues due to your path definition
    1. I’m using mcnp_endfb70 data library

I could send you by email zipped output folder if you want to extend your check.

regards
