Hi,
I am new in the forum and in GMSH. I don't understand why Gmsh turns my structured mesh into an unstructured one. I attach the file. geo in extension .txt. Thanks in advance for your help. Regards, Andrea |

Gmsh requires all surfaces to have at most 4 constituent points/lines to provide a structured mesh. You have to subdivide your geometry in surfaces where you have no more than this number of points/lines.

Besides, you have to recombine all your surfaces. Please check the tutorials from Gmsh. There you can see how to recombine the elements to get a structured mesh. In short, you have to transfinite your surfaces and then recombine. Best of luck.
