I created a 2D mesh using Pointwise, and extruded 15 degrees using the rotate function. After that, I want to export into .cas file to run my simulation, it shows:

Error: Face processing failed.
Info: Check your grid for one of the following invalid situations:
Info: * Incompatible BC types used on opposite sides of a baffle or connection.
Info: * Non-manifold connectivity.
Info: The unmatched faces have been written to the VRML file: MY FILE
Info: Import this file as database to locate the problem areas in the grid.
Warning: Aborted Export CAE.

May I know what is the problem that I should change here? My version is V18.4 Release 3. I am attaching the screenshots of my geometry. Your help is highly appreciated, thanks!
