Hello all,
Would anyone know of a good tutorial or thread that addresses the following issue? So far I have found these but the solution is not clear to me: http://www.cfd-online.com/Forums/ope...tml#post332307 http://www.cfd-online.com/Forums/ope...blockmesh.html http://www.cfd-online.com/Forums/ope...nal-faces.html My mesh is generated by blockMesh, however when I try to define an internal face as a wall or patch in blockMeshDict I get the error: --> FOAM FATAL ERROR: Trying to specify a boundary face 4(151 153 15 13) on the face on cell 76 which is either an internal face or already belongs to some other patch. This is face 0 of patch 3 named internalWalls. I would like to create a 0 thickness wall. This face is between two meshed blocks. The 4 vertices that make up the face (151 153 15 13) are used to define both blocks and are not duplicated. Is there a general method for defining 0 thickness internal walls? I am working with OpenFoam 2.1.1 Thanks for your advice. UPDATE: Solved by duplicating existing points on internal face and incorporating into hex blocks. Runs stable.
