Title
Question
Hello Everyone...
I am very new to OF and trying to mesh a cylinder for Hagen-Poiseuille flow. I am getting error like:

FOAM FATAL ERROR:
face 7 in patch 0 does not have neighbour cell face: 4(19 20 24 23)
From function polyMesh::facePatchFaceCells(const faceList& patchFaces,const labelListList& pointCells,const faceListList& cellsFaceShapes,const label patchID)
in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 127.

Actually I tried to correct the order of points and still i got the same error..
Also, when i tried with "paraFoam -block", paraview opened and closed before showing anything.

How to rectify this..

blockMeshDict is :
convertToMeters 0.1;

Answers:

Hi, I think there is some problem in numbering of the vertices while you generated the blockMeshDict file. This problem is either where you specify the boundary face or when you specify the blocks. Please check the file properly with a diagram of the pipe along with the vertices and I am sure you will find the mistake.

Hello all

I had problem high courant number, using the files downloaded for this case, and i solved it only modificating

deltaT 1e-06; and the writeInterval 50000;

but if you dont have a good cpu, or dont know how to use multiple servers, you can spendt several days (up to 7)

Best regards
