Greetings,
I've been using GID to mesh a SAG mill (just surfaces, not volumes) and always get this same error when executing on LIGGGHTS:
Some elements with:
Mesh cad2: element id 146249 (line 1023745) has 6 neighs, but only 5 expected
And then it fails showing this:
ERROR on proc 0: Fix mesh: Bad mesh, cannot continue. Possibly corrupt elements with too many neighbors.
If you know what you're doing, you can try to change the definition of SurfaceMeshBase in tri_mesh.h and recompile (../surface_mesh_I.h:504)
I've already done a simulation without issues, but now this started, yet I've always have had this 6 neighs problem
If anyone could help me with a suggestion would be much appreciated.
Best regards.

Re: Problems with meshing on GID and executing on Liggghts
These messages are raised by LIGGGHTS, not by GiD.
We don't know its meaning or the limitations of this code (6 triangles around a node is the most common pattern of a triangle mesh)
If the numeration of elements written for LIGGHTS is the same of GiD I recommend you to try to visually identify the problematic element 146249
(you can identify an element with Utilities->Signal->Elements)
and can list it with Utilities->List->Elements
Maybe you will see some unusual in this element.
Have a look also in yourLIGGGHTS calculation file, in the related line number 1023745, maybe something is wrong.
