To remesh imported meshes, add another Mesh sequence and use either a physics-controlled or a user-controlled mesh, as shown in Figure 8-24. With a volume mesh in the domains, the mesh is ready to be used for simulation. The physics is applied to the domains and boundaries defined by the mesh, so no geometry is needed.

To remesh boundaries in the sequence where the mesh has been imported, for example to give better results in the Booleans and Partitions operations, use the operations Remesh Faces (3D), Remesh Edges, and Remesh Domains (2D).

Yet another alternative, is to generate a geometry from the imported mesh before creating a mesh for simulation. For more information about this workflow, see Creating Geometry from Mesh.

Run the Cleanup Wizard to remove small details in the geometric model of the mesh. It will detect small details, such as:

To open the Cleanup Wizard, choose one of the following:

The details will be removed using mesh operations, for example some of the Cleanup and Repair and Entities operations.
