Input temperature map as boundary condition for neutronics simulation

Hi,

I’m trying to couple openmc with a CFD solver. I think this has been done before by another researcher but the research paper does not go into the details of the inner workings. Please see below link.

I have a run an isotropic neutronics simulation to get a power distirbution in a structured mesh. i’ve interpolated this onto my cfd mesh. and i have run my simulation and gotten a resultant temperature map.

I’d like to input this temperature mesh into openmc & run the neutronics simulation again to get an updated temp.

can someone help me figure this out please?

thank you
siddarth

Hi @siddarth_fusion and thanks for your first post! We have been working on MC-CFD coupling at ANL as part of the DOE Exascale Computing Project. I’d encourage you to read our recent paper in Nuclear Science and Engineering (available for free):

The coupling code that we are developing is also available on github:

After looking through those, let us know if you have specific questions.
