Hello everyone,
First, congratulations for your works. I have used Gmsh since my
undergraduate studies and I still use it in Phd.
My problem is the following:
I had to remove with duplicates vertex in an .msh mesh. The command,
"gmsh -check mesh.msh" was able to find duplicates vertex but "Coherence
Mesh;" does not delete them.
Anyway, I wrote a python script which find and delete them using the
output of "gmsh -check mesh.msh".
Then, my mesh does not have any duplicates vertex but the node numbering
is discontinuous.
The command "gmsh -renumber mesh_without_duplicates.msh" is able to
renumber nodes but it launches gui and to save the renumbered mesh, I
have to click to "Save Mesh".
I would like to find a way to save the renumbered mesh without launching
Gmsh gui. In order to be totally executable from prompt.
I already tried:
- "gmsh -renumber mesh_without_duplicates.msh -2 -order 2 -o
renumbered.msh"
It works but the mesh vertex are altered due to mesh regeneration and it
leads to unacceptable modification of the mesh.
I also tried some :
"gmsh -renumber mesh_without_duplicates.msh -string 'Save
"renumbered_mesh.msh";'
But It saves an empty mesh. In fact, specificity of my problem (and
source of complication) is that I had to work with .msh file directly
and not .geo file.
However, I think that to have a command line -save_mesh renumbered.msh
available after -merge, -renumber, -coherence actions can be very
interesting. I searched in documentation but I did not find any command
like this.
Thank you again.
Christophe
