Zmesher is able to generate 3D cartesian meshes of volumes, surfaces, lines and/or points. It is especially suitable for electromagnetic simulations of Finite Differences.
Tutorial can be found at: User Manual->METHODS FOR MESH GENERATION->Cartesian mesh
Zmesher has been implemented by a third part partner (University of Granada), and the first time that is used it will require an extra password
To set as mesher: Zmesher is needed to go to Preferences window and first from Mesh->General choose Cartesian inside Mesh type, and after apply, select Zmesher from Mesh->Cartesian
When you generate the mesh and is the first time that this mesher is used this window ask a password
The password could be freely obtained from the related web (and will be stored in the file scripts/TemporalVariables, to not ask it again)
