Face merging, patch definition, wall function
I have a problem using blockMesh:
I want to attach a cylinder face to a bigger rectangular block face using the command "mergePatchPairs".
The goal is, that the cylinder face is completely merged to the block face, whereas the remaining block face should become a wall with wall functions applied.
That's my question:
How should I define the patches and boundary conditions?
I already tried it, but it did not work. That's how I defined everything:
(1 2 3 4)
(5 6 7 8)
Boundary file 0/epsilon (i.e.):
value uniform 0.000765;
I got the following error:
"Invalid wall function specification
Patch type for patch bottomface must be wall
Current patch type is patch"
What does it mean? I defined the block face as a wall!
Can anybody help me with this?
The patches are defined in the blockMeshDict file.
I solved the problem by deleting and recreating the boundary file.
No everything works well :-)
