Wrap surface
 

I need to solve a hydrodynamic problem without symmetry. So i create a block volume as control volume with the hull inside this volume.

When I begin meshing I do not know how to maintain the hull in the mesh because the hull disappear from the mesh.

Selecting the wrap surface is in largest internal but other options doesn`t work.

Does anybody know how to work with this kind of geometries (control volume + complex surface for external flows simulations)?

Thanks!

Custom size the mesh in your hull geometry.
