### 9.8.4. Importing Multi-domain Cases

Meshes intended or previously used for multi-domain simulations can be imported into CFX-Pre. You will still be able to set up a multi-domain simulation from a single mesh import.

If the imported mesh is not connected, a separate assembly will be created for each connected section. Each assembly can be used to create a separate domain. If the mesh is connected, then a single assembly will be created but 3D primitives will be created for each 3D region defined in the mesh file. Each 3D primitive can be used to create a separate domain, even if it is contained in a single assembly.
