this task uses a surface and volume mesh https://github.com/fusion-energy/neutronics-workshop/blob/main/tasks/task_20_CAD_shut_down_dose_rate/1_unstructured_mesh_R2S_shutdown_dose_rate.ipynb it should do the mesh like this example so that it is conformal https://github.com/fusion-energy/cad_to_dagmc/blob/main/examples/surface_and_unstructured_mesh/unstructured_mesh_with_conformal_surface_mesh.py
