FLUENT 6 - Cannot change [...] to interior because there is only one adjacent cell thread
|
When reading a mesh file into FLUENT an error is reported: Error: Cannot change [a boundary zone name] to interior because there is only one adjacent cell thread. This error occurs when an edge, in 2D, or a face, in 3D, is assigned the boundary type interior in Gambit when that edge/face only has a fluid region on one side. If your mesh is intended to have fluid on both sides of this edge/face, then open Gambit and check for a duplicate edge/face. If you find there are two at the location of interest, then use the cleanup tools to remove the duplicate: <a target=_blank href="http://www.fluentusers.com/gambit/doc/ori/html/modeling_guide/mg0504.htm#tools_cleanup_dup_geom">http://www.fluentusers.com/gambit/doc/ori/html/modeling_guide/mg0504.htm#tools_cleanup_dup_geom</a>http://www.fluentusers.com/gambit/doc/ori/html/modeling_guide/mg0504.htm#tools_cleanup_dup_geom Avoid this problem in the future by ensuring that adjacent faces share a common edge if fluid is intended to cross the shared edge. |
