Hi!

I'm trying to use gmshToFoam to convert a mesh. I get an error, and I don't know what it means. Does it mean I need to have volumes, not just surfaces? Does it mean the meshing didn't work out? Or something else? I can attach something else if I need too. Thanks!

Here's an image of the mesh:

Here's the entire output of the command:
Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

--> FOAM FATAL IO ERROR: 
No cells read from file "mesh.msh"
Does your file specify any 3D elements (hex=5, prism=6, pyramid=7, tet=4)?
Perhaps you have not exported the 3D elements?

file: mesh.msh at line 129.

    From function void readCells(const scalar, const bool, const pointField &, const Map<label> &, Foam::IFstream &, cellShapeList &, labelList &, List<DynamicList<Foam::face> > &, labelList &, List<DynamicList<label> > &)

Hi,

Basically to have cells in a mesh you have to define physical volume.
