Hello, does the DAGMC export feature only export a surface mesh? Im trying to run mesh tallies on OpenMC and when I use DAGMC export it is only exporting the surface mesh not my tetmesh.
Thanks
Hi @thallam,
yes the DAGMC export does only export the surface meshes.
So you would need the tetmesh for OpenMC in the .h5m?
Correct, I believe for the unstructured mesh tallies for openmc it requires a volumetric tetmesh so openmc can tally the data onto the mesh. As I understand there are two ways to utilize unstructured meshes in openmc. The first being the .h5m and moab and the other is .e and libmesh. I have tried the libmesh way but im running into errors on writing the data to the exodus mesh but I cant utilize the moab way because cubit is exporting the surfaces only.
Do you know how the data structure for the mesh should be in the .h5m?
