Rebuild Mesh
The Rebuild tool streamlines the process of remeshing existing meshes to generate a new mesh with good quality and flow. The rebuild mesh functionality utilizes the same parameter and criteria files used by BatchMesher to define the quality criteria and relevant mesh parameters. This algorithm saves significant time over the traditional automesh and quality correction approach.

Rebuild is currently supported for first-order FE meshes that are not associated with geometry or attached to 3D element faces. 1D features (plot elements) are important for defining the mesh topology. These features are utilized as vertices, edges and faces, in a similar way to geometry, during the rebuild operation. Such features are generated automatically by the Midmesh tool or can be manually created. If 1D features are not defined on the mesh, they will be automatically generated internally.
