Import Gmsh

[michalacadova]

Hi,
I have problems importing a meshed geometry from GMSH. I am using the recombine mesh, i.e. not the triangle/tetrahedron, but the quads/ prism. But since both are kind of volumetric mesh I don’t see the reason, why it should not import it. With the mesh made of tetrahedrons it works fine. But now I am having problems – the PreView just crashes.

I have several notices that I have realised until now (it is also mentioned in the manual or elsewhere in the forum, but just to sum up): Preview still recognise only the extension *.gmsh, not *.msh, only the $MeshFormat “2” not “2.1” or “2.2” is accepted, and only $Nodes nor $ParametricNodes are supported. Is there something else that I should keep in mind while importing the geometry from Gmsh?

I have attached two files – one that PreView can read and one that it can’t.

Hi Michala,

There was a small bug in the GMsh reader that was causing the problem. It's easy to fix so I'll try to get it done today. About the extension, I'm not too familiar with the gmsh program so what is the default extension that the program uses? Is it .gmsh or .msh? If it uses both I can support both in PreView as well. Just let me know what you would prefer.

Thanks,

Steve.

PS: the fixed (windows) executable is available

Hi,
the default extension is *.msh.

Ok, thanks. I'll make the change.
