Segmentation fault

[Sofia-Y]

Hello,
The hexahedral elements work fine (neper -M n1111-id1.tess -elt hex -format 'inp' ). However, I keep getting a segmentation fault when I try to use tetrahedral elements. As follow are my commands:

neper -T -n 1111 -id 1 -oricrysym cubic -ori uniform -format tess
neper -M n1111-id1.tess -elt tet -format 'inp'

Also, another example that worked for hexahedral elements and not tetrahedral elements is as follow:

neper -T -n 111 -id 1 -oricrysym cubic -ori uniform -format tess
neper -M n111-id1.tess -elt tet -format 'inp'

Did you run the tests (make test)? These errors typically indicate that Gmsh is unavailable or broken. Hex meshing is done by Neper itself, only tet meshing uses Gmsh.

If you mean (c make /make /make install) then yes I did run those during installation.

Thanks.

No, I mean make test, which runs the tests (those you mentioned are for configuration / compilation / installation).
