createPatch and splitMesh problem
 
Hi Foamers,

I am creating a geometry out of 5 different geometries. I used mergeMesh and stitchMesh to create the final geometry. Then, I create a faceSet using setSet utility. I want to assign a fan boundary condition to this faceSet. So,

1. I run the splitMesh, after updating my boundary file with two patches having 0 faces. (fan_master and fan_slave).
After running splitMesh, I have the following message
Code:

<<Number of duplicate (not baffle) faces found: 1. This might indicate a problem.
  <<Number of faces with non-consecutive shared points: 1. This might indicate a problem.
Writing mesh to 1

2. I run createPatch utility
Then, i run into this error
Quote:

--> FOAM FATAL ERROR:
Face 7221101 specified in set fanFaces is not an external face of the mesh.
This application can only repatch existing boundary faces.

From function createPatch
in file createPatch.C at line 714.
I don't understand why this error is coming up. Can anyone help me?

Solved!!
 
I got the solution to this problem. Apprantly, I did not make the correct entries in the createPatchDict.

Thanks,
Dhruv.
