Cyclic BCs using createPatch in OF 1.6.x
I have been trying to implement cyclic boundary condition for a 22 blade turbomachine using createPatch in OF-1.6.x for simpleSRFFoam.
My createPatchDict is as follows;
When I execute createPatch, I get the error;
I have tried:
1. Change patch type from 'cyclic' to 'patch' in the polyMesh/boundary file - found in example file of createPatchDict under $FOAM_UTILITIES/mesh/manipulation/createPatch
Although this succeeds in createPatch, the same error (as above) occurs when checkMesh is executed.
2. loosen match tolerance to get case to load
Same as above, createPack OK but same error remains at checkMesh.
I was wondering if anyone has encountered similar issues and was hoping to gain insight into the above issue.
Any help is greatly appreciated.
I have been able to solve the problem by overwriting the whole <case>/constant/polymesh by <case>/<timestep>/polymesh folder created by running createPatch (where <timestep> directory is named as the timestep configured in controlDict).
I don't really understand how to use the createPatch utillity. Well it worked, but may anybody explain me please:
I have created a rotational periodic mesh in ICEM. Then I have converted the meshfile with fluent3DMeshToFoam.
The two periodic faces do have the type 'wall' in my file polymesh/boundary. Now I change them into 'patch'.
Then I run my createPatch file:
Now I dont really understand what to do. I have tried a few things to start a calculation, but without success.
Maybe somebody who has already dealed with this application can give me a quick advice what to do next :) thanks!!!
