Overlapping Hybrid Meshes

For cases of substantial motion of part of a geometry (e.g deployment of flaps, rotation of a propeller, store separation, etc), the use of a separate grid attached to the part of the geometry in motion may be an alternative approach. Overlapping meshes allow for prisms/hexahedra to grow from a certain part of a geometry, such as a flap or blade, ignoring the presence of neighboring solid boundaries. These elements then overlap with the elements grown from other portions of the geometry such as a wing or spinner. The result is a mesh that allows for large scale motion without mesh regeneration.
