FOAM FATAL ERROR: Inconsistent number of faces blockMesh::createMergeList() line 193
 
Hallo!
I have got some troubles with blockMesh:

// ************************************************** *********************** //
If I replace the values for the meshrefinement from (10 1 1) to (1 1 1), see below, then blockMesh will work
Code: hex (0 1 5 4 16 17 21 20) (1 1 1) simpleGrading (1 1 1) // Block 0


Can anyone help me to solve this problem?


I guess there can be a problem with the block IV coz it is positioned in the middle of the geometry and around there are all other blocks. The block IV does not have any contacts to the walls



Thanks for your support


best regards


Franz
