Dear developers team,
My research is devoted to combined calculation method in reactor physics.
I met with documentation about cmfd in your Theory and Metodology chapter but as I understand i can create only square mesh to perform transport calculation. Is it possible to construct more complex meshes in XY plane (hex-Z for example) ? I m appreciate for any answer about the combined calculation method.
You can create arbitrarily complex geometries with OpenMC, including hexagonal lattices. The mesh over which diffusion parameters are generated for CMFD acceleration can only be a regular structured mesh however. Hope that helps resolve the confusion.
Best regards,
Paul
