[CIG-SEISMO] python LibGmsh2Specfem_convert_Gmsh_to_Specfem2D_official.py

[Wouter Kimman]

Dear Paul,

See the attached .msh file.
I'm using gmsh 2.6.1 (windows version, had problems compiling on linux) and Python 2.4.3 (linux)
Regards, Wouter

Dear Wouter,

It is working with the provided .msh file. So can you send your .msh file ? It seems that it is not correctly generated. Which version of gmsh are you using and also which version of python ?

Thanks

Best regards

Paul Cristini

Dear Specfem2D users and developers,

My question is regarding the use of Gmsh for SPECfem2d. I was unable to reproduce the mesh given in the example (SqrCirc.msh). If I load the .geo file in Gmsh, compute the mesh and run the python file I get the error listed below.

I expect I'm doing something wrong in the generation of the mesh since I don't have this error if I use the existing .msh file (also the mesh looks different).

Any pointers as to what parameters in the Gmsh generation I should change to obtain a working mesh? Or does this suggest there is error in the python script?

Thanks and best regards,
Wouter Kimman
