Icepak FAQ: Non-conformal + inclined objects
When meshing Icepak uses bounding box of inclined object to work out intersections with assembly,
This can lead to spurious warnings - eg:
Inlet has a shape that cannot intersect an assembly - ignoring intersection region.
And can lead to problems when taking the model into Fluent when generating the interface (in my case it was ok when inclined object not close to the assembly, but failed when inclined plate was close to the assembly bounding box).
To get round this, divide the inclined plate so that it's bounding box does not intersect the assemblies bounding box.
