Creating .msh files

[Wendy María Arango]

Hi.
I’ve been trying to create a scene with VTKExporter and MeshVTKLoader, but when I finish and run it, I get a segmentation fault.

I’d like to know how to solve it.

Otherwise, what are you using to create .msh files?
I haven’t found a good app to do it.

I saw your MeshGmshLoader example but, as I said, I haven’t found a good app to create .msh file.

Thanks for your help.

Regards.

Tetgen is a good application. I have used in a lot in the past.
Check out this link. http://wias-berlin.de/software/tetgen/

I usually pass it a STL file and it generates all the data for you to create a msh file. You need to combine the output from tetgen which are elem and node data.

hey @warango and thank you @vmenon for the input!

Did you succeed in creating your mesh?
Do you need further assistance with SOFA?

Best,

Hugo
