import/export of mesh

pf4d

Hello,
Is it possible to import or export the mesh used by ISSM? I would like to convert between formats for comparison with other FEM codes.

Thanks,
Evan

Hi, Evan
If you want to export mesh from issm, you just look up the 'md.mesh' in issm. Maybe exporting mesh is dependent on format of other mesh type. As I know , there is no function in matlab to exporting mesh.

Let me know the mesh type which you want to import or export. I try to look up any matlab tool box which could supports exporting or importing

Thanks

Hi Inwoo,
I noticed in the compilation script that Gmsh is installed; I have scripts to convert between many different FEM-mesh formats, including .msh used by Gmsh. Basically what I was looking for was any information on the mesh-exporting options of ISSM, as there may be a format output that I can convert with zero effort.

Otherwise, I'll have to---like you say---investigate md.mesh and convert manually (which maybe not too difficult anyway).

Thanks for helping,
E

Hi Evan,
yes you can use meshconvert to import your mesh:

md=meshconvert(md,index,x,y);

This function is also implemented in python. In terms of export, we did not write anything in the code because it depends on the format you want, but it should be really straightforward. You can take a look at src/m/contrib/morlighem/bamg/YamsCall.* for example.
