node numbering

[neri alamanni]

Hi all
I have a model producing a crash in Elmer Solverin loading model itself. The files mesh.nodes, mesh.elements, mesh.boundary look correct. The only thing to note is node numbering that is not continuous i.e. has gaps (node id 1,2,3,5,8 etc.) but connectivity is ok.
So must the node numbering be continuous? Is there a way to have a better diagnostic to understand what is wrong?
Thank you

Hi

Node numbering must be continuous i.e. all numbers are used.

Should that apply for mesh import also? I have just opened a mesh file in gmsh .msh format with non-continuous node numbering without apparent problems.

Hi Matthias

ElmerGrid should take of this usually. You should see it in output because of the line:

Code: Select all

    printf("Renumbering the Gmsh nodes from %d to %d\n",maxindx,noknots);

The constraint conserns meshes being read in by ElmerSolver.

I see. Thank you for clarifying this.
