Converting axisymmetric mesh into fully 3D mesh
 
Hello Foamers,

I am trying to generate a cylinder by 'revolving' my axisymmetric mesh through 360 degrees. I am using extrudeMesh and I get the following error:

Assuming full 360 degree axisymmetric case; stitching faces on patches frontAndBack_pos and frontAndBack_neg together ...

--> FOAM FATAL ERROR:
no points or no cells in mesh
point, face or cell zone already exists

From function void addZones
(
const List<pointZone*>&,
const List<faceZone*>&,
const List<cellZone*>&
)
in file meshes/polyMesh/polyMesh.C at line 987.

I was wondering if someone could shed some light on the case setup, ie: extrudeMeshDict and wedge coefficients etc. I'm finding it difficult to gather information on this...

Kind Regards,
Thomas Loh
