Re: Compute a mesh

Posted by Walliston Fernandes at January 27. 2016

Hi to everyone!

I need to compute a mesh from Nastran (.dat) and there were some errors. I tried to convert .dat to .med file using Gmesh in order to import to Salome, but some formats of mesh shows a problem. Does anyone know how to proceed and generate a mesh without error?

Link for the mesh: https://www.dropbox.com/s/252w3yptm8h7vqw/basic_ESO_tria2d_Nastran.dat?dl=0

 

Thanks for any advice

Hi Walliston

You have a not closed 2D mesh in that file. What mesh do you need to generate, a 3D one?

Hi Saint Michael,

I would like to generate a 2D mesh. Does Salome work only with a closed mesh?

 

Thanks

If your problem is how to import a nastran mesh into salome, I'd suggest to store the mesh in med format using gmsh.

Hi, St. Michael,

When I change the mesh format to a .med file, Salome computes the mesh, but a message appear and there isn't a visualization of the mesh. Do you know how to proceed?

Thanks for help me,

Hi Walliston

There is no need to compute the mesh after the import, just show it. May be you need to FitAll to see the imported mesh.
