eric.m.tridas is on a distinguished road
I created a mesh using Gmsh then used the makeAxialMesh utility to create a wedge. I run in to issues when trying to run my solver with the following error message:

Code:
    Creating particle cloud
--> FOAM Warning : 
    From function tetIndices polyMeshTetDecomposition::triangleTetIndices(const polyMesh&, label, label, label)
    in file meshes/polyMesh/polyMeshTetDecomposition/polyMeshTetDecomposition.C at line 643
    No base point for face 0, 4(3520 13070 1890 295), produces a valid tet decomposition.
--> FOAM Warning : 
    From function tetIndices polyMeshTetDecomposition::triangleTetIndices(const polyMesh&, label, label, label)
    in file meshes/polyMesh/polyMeshTetDecomposition/polyMeshTetDecomposition.C at line 643
    No base point for face 0, 4(3520 13070 1890 295), produces a valid tet decomposition.

...
When I perform checkMesh I get the errors:

Code:
***Zero or negative face area detected.  Minimum area: 0
<<Writing 389 zero area faces to set zeroAreaFaces
and

Code:
***Max skewness = 6.66666666667e+296, 389 highly skew faces detected which may impair the quality of the results
<<Writing 389 skew faces to set skewFaces
Is there a utility to remove the zero area faces? I believe that this is what is causing the tet decomposition errors.

Hi,

Did you run the collapseEdges utility after running makeAxialMesh? If I remember correctly, I think makeAxialMesh tells you to run this.
