** ERROR 2002034 ** Can not find interfaces between core or cavity name1 and core or cavity name2 . The cavity and the core are too far apart or oriented the wrong way. Please check the model for errors or increase the surface matching tolerance value under core shift tag.
The cavity and the core are too far apart or oriented the wrong way, so the solver can not find the interfaces between them.
Fix the model or increase the surface matching tolerance value on the Core Shift tab of the Solver parameters.
