Coreform Cubit now supports the import of OpenMC constructive solid geometry (CSG) geometries as CAD entities. OpenMC CSG geometries can now be converted to a Cubit journal file through a script available at the OpenMC github. This enables CSG to be represented as 3D CAD geometry in Cubit. Both the entire CSG model and sections of the model can be selected for visualization and inspection, as well as for enabling the geometry to be used for other downstream CAD and CAE applications.
See examples and more details of this workflow in this Google slide deck.
