Hello foamers,
With extrudeMesh utility I am trying to extrude 2D mesh to 45° wedge with multiple layers in circumferential direction. I was following this tutorial ( https://openfoamwiki.net/index.php/Mesh_Generation_for_3D_Axisymmetric_Problems ), but I wasn't able to duplicate their results. The extruded mesh is always only one cell thick. The tutorial was written for OF 2.0 and I am using OF 4.0, so there could be some changes in usage of extrudeMesh.

My extrudeMeshDict:

Code:
constructFrom patch;
sourceCase ;
sourcePatches (frontWedge);
exposedPatchName backWedge;
flipNormals false;

extrudeModel        wedge;


nLayers             5;

expansionRatio      0.9;    //0.9

sectorCoeffs
{
    axisPt      (0.005 0 0);
    axis        (1 0 0); 
    angle       30;
}
mergeFaces false;   //true;
mergeTol 1e-5;
The frontWedge lies in XY plane and backWedge lies in possitiv direction of Z axis.

The whole case can be downloaded here: https://drive.google.com/file/d/0B-d...ew?usp=sharing


Thank you for your hints.
Best Regards
Jiri

Trying to change the keyword "wedge" to "sector".
