[Gmsh] Gmsh to Paraview

[Serban.Georgescu at uk.fujitsu.com]

Hi Yosuke,

A while ago I have written a code to convert some other file format, similar to gmsh, to Unstructured VTK (VTU) format.
What you are trying to do seems very similar, and I did not have any problem with the converter.

What exactly does not work?
Does the converter crash? Does paraview crash when opening the file? Do you get the wrong shape in Paraview?
If your problem is one of the last two, you could do a very simple shape (e.g., one tetrahedral), generate a VTU file in ASCII format and look at it in notepad.

Cheers,
Serban

Dear All

I am trying to write visialisation code of gmsh file in Paraview. I thought to create the geometry in Paraview just copying connectivity and coordinate from gmsh file. Obviously, need to add cell type and offset values for Paraview. However, it did not work.

The element type I am interested is tet4. The code automatically detect volume element section and read connectivities. Points, lines and surface connectivities are ignored. All Coordinate positions are scanned too.

I tested my code by hand specified coordinate and connectivity and it worked without any issue.

I am not familiar with mesh algorithms can anyone give me what could be the reason ?

Best Regards
