[Gmsh] Structured mesh of a STEP part

[Zenker, Dr. Matthias]

Hi Daniel,

have no experience with structured meshes, so I cannot help you here. But maybe someone else knows more  - CC of this answer goes to the gmsh mailing list.

Hello Mattias,

Thank you for your answer!

I'll try to explain a bit more.

I have a STEP part and when load it into gmsh, I'm able to mesh it directly by doing: Mesh -> 3D. However the mesh I obtain is an unstructred and I need a structured mesh.

My file has only one volume and about 25 surfaces. Therefore this part contains many lines.

If I got it right, in order to generate a structured mesh I have to use the "transfinite line" to define the number of nodes of each line.

So my question was, Do I have to define the number of nodes of each line manually (using transfinite line) or there is a clever way to do so?

Thank you very much for your help,

Sincerely,

        Daniel
