Mapped mesh

Dear Edgar,

Thank you very much for your suggestion. However even in the model you sent me only the boundaries get meshed and when I try to mesh the domain outside the wire (Domain 1) using the Free Tetrahedral Mesh I get an error saying that the "Boundary mesh must consist of triangular elements only." How do I mesh the domains in the model using your method please?

Thank you for your answer,

Lucie
