How to change patch types in snappyHexMesh?
I am meshing using snappyHexMesh for the first time.
I have a *.stl file wherein i have defined 3 solids - wall, inlet, outlet (those are the names given to the solids)
when running snappyHexMesh this is part of the output
Adding patches for surface regions
Patch Type Region
----- ---- ------
6 wall xyz_wall
7 wall xyz_inlet
8 wall xyz_outlet
Added patches in = 0.02 s
As you can see it has defined all the three boundaris as "wall" but inlet and outlet (of a pipe for example) are always defined as "patch". So how do i change the patch type of "inlet" and "outlet"?
Do i need to change only the boundary file in constant/polymesh? Or is there any other way to define it using snappyHexMesh - I saw something called as "patchInfo" in SHM but not sure how to use it to define different patch types to different boundaries.
I just stumbled upon this post and think I know the answer, if it is still needed.
If you refer to https://github.com/OpenFOAM/OpenFOAM...ppyHexMeshDict you can see, that there is a patchInfo entry in "refinementsurfaces". If you don't set the patchInfo entry, SHM will refer to any given .stl-patch as "wall" by default.
So all you need to do is give it the patchInfo like this:
Hope that helps,
