[Gmsh] Problem saving a 1D mesh with groups

[DILASSER Guillaume]

Hi Miguel,



The explanation is in Gmsh doc there : http://gmsh.info/doc/texinfo/gmsh.html#Elementary-vs-physical-entities. When you save a mesh, if at least one Physical group is defined, then only those get saved, otherwise the whole mesh is saved. Therefore, I think you are missing the definition of a Physical line for the line that connects your Physical points, resulting in you only saving the endpoints.



Sincerely yours,

Hi



I'm trying to create some groups and a 1D mesh with gmsh.  I import the mesh from an .iges file and then I create the groups (Physical Points).

After that I create the 1D mesh and everything seems ok, the problems is when I save it, only a cople of nodes and elements show in the mesh. If I mesh it without defining the groups, all the mesh is correctcly saved.



Is this a bug? I'm doing something wrong?



This are the files:

Thanks
