Hello everybody,

I would like to mesh the inner volume of the following stl file (which i got here) with GMSH.

I know I have to merge the stl geometry, create a new volume by selecting the surface of the stl and mesh it, but it only meshes what's for me the "walls" of the geometry. What I would like to do is meshing the inner volume to do some fluid simulation in it. Could someone help me find a way to do it?

Thank you!

Hi,

the problem seems to be that your entire geometry is seen as just one surface by gmsh.
I think you have to make several surfaces out of your stl and close the ends of your geometry with additional surfaces. But I don't know how to do that. gmsh is not able to save the stl in its own geo format (at least for me).
I would suggest you post this question on the gmsh mailing list at http://www.geuz.org/mailman/listinfo/gmsh/.

HTH,

Matthias
