Error when running Tutorial 1 using `domain.msh`

Open MattRolchigo opened this issue 2 months ago • 0 comments

When I run Tutorial 1 using the provided mesh file (rather than creating a mesh), I get the following error:

    void dealii::GridIn<3>::read_msh(std::istream &) [dim = 3, spacedim = 3]
The violated condition was: 
    cells.size() > 0
Additional information: 
    While reading a gmsh file, the reader function did not find any cells.
    This sometimes happens if the file only contains a surface mesh, but
    not a volume mesh.
    The reader function did find 192 lines and 1536 facets (surface
    triangles or quadrilaterals).

I'm using the nix build and running using MacOS. I've tried specifying mesh_format as default and gmesh, but get the same error message.
