CFX GGI Interface Error (non-overlapping)
Hello, I have a little issue and I was wondering if their is a way to solve this problem. I am using CFX v11 and I would like to interface two similar faces which lay on the same plane (Y,Z) however are in different rotational locations (Rotation Axis, X). So I would like to extract the temperature from FaceA, rotate it about the X axes some angle theta, and map it to FaceB. I tried using rotational periodicity, however this failed because the faces are normal to the rotation axis so CFX gives the following error.
+--------------------------------------------------------------------+ | ERROR #555000003 has occurred in subroutine CS_COMPUTE. | Message: | | GGI intersection error. For a particular boundary face on domain | interface: | | INTF_FACEA_FACEB | | The intersection failed to find any pixels. Likely causes are: | | 1) Very large differences in grid density between the two sides of | the interface. In this case, increase the value of the expert | parameter 'ggi bitmap resolution'. | 2) An interface contains a degenerated face. In this case, also | increase the values of the expert parameters | 'ggi bitmap resolution' and/or 'ggi edge scale factor'. | 3) A sliding interface has one or more nodes with zero radius. | In this case, modify the grid to remove these nodes. +--------------------------------------------------------------------+ Any suggestions or examples using CEL or Fortran would be greatly appreciated. I do not have access to CFX v12. Thanks in Advance, Sergio |
Hi,
If you define the sector using periodic boundaries and link them a GGI this should work. You might need to post an image to help us understand what you are trying to do. Glenn Horrocks |
