Hello,

I want to mesh a stl file but any time I try Netgen creates a surface mesh.
At the beginning I thought that the volume mesh is just not shown when I used the clipping function because it did only show an empty inside. But I was not able to convert the mesh to the foam format. That's why I guess that the mesh information is not adequate (not a volume).
It always shows the message: "Trying to get back from bad stream"

Is there a way to mesh a volume out of a surface mesh or from a stl file with Netgen or any other Mesher?

Thanks a lot!
