Zmesher cartesian mesher

Current GiD includes two Cartesian algorithms: 'Scan convert' and 'Zmesher'.

 

Zmesher can generate 3D Cartesian meshes of volumes, surfaces, lines, and points. It is especially suitable for Finite Difference electromagnetic simulations.

Zmesher was implemented by a third-party partner, the University of Granada.

In the Preferences window, set the mesher to Zmesher and disable the User defined grid option. Then, generate the mesh again with a general mesh size of 2.0.

When the mesh is generated, the following information is displayed.

 

Now, the mesh will also contain quadrilateral faces for the isolated surfaces.

In fact, this mesher could create some 'degenerated' cells, to preserve topological connections. E.g. 1 line element is generated although there is not any isolated geometrical curve, and also 1 extra quadrilateral is generated from a volume.
If the 'Avoid degeneration' option is set, then these degenerated elements are automatically deleted.
