CFD Online Discussion Forums - [blockMesh] 3D mesh contains invalid faces?

Hey Guys,

I want to compute some kind of flowcell for a project, but there is some error that I cannot solve on my own.

The flowcell consists of 3 inner tubes and the flowcell itself aranged around the middle one of these inner tubes. The tubes themselves consist of 8 blocks each.

After I run blockMesh, the mesh was shown properly in paraView, so I run simpleFoam.

This is the error shown by simpleFoam:

Code:

--> FOAM FATAL ERROR: 

This mesh contains patches of type empty but is not 1D or 2D

    by virtue of the fact that the number of faces of this

    empty patch is not divisible by the number of cells.



    From function emptyFvPatchField<Type>::updateCoeffs()

    in file fields/fvPatchFields/constraint/empty/emptyFvPatchField.C at line 150.

CheckMesh reports one invalid check too, so there must be some mistake involving the faces of the mesh? But I thought, the internal faces in the flowcell should be empty?

I attached all the logfiles and also my blockMeshDict (comments are in German, if you need the translated version, i will translate it).

Please help me to get an idea of what I made wrong.

Kind regards,

Florian
