Hi Peter! I am using SW 2014 and:

Is the square frame on top (which is not united with the casing) the inlet?  Is the tube at the bottom the outlet?

Of course they are, and are supposed to be united.

 The last mesh was for a rotor and housing where I could define a fixed boundary in the fluid to separate the mesh for the rotor and the mesh for the stationary section.  That is not possible for this type of pump.

I am unable to understand that.

Is there any special reason to export in parasolid instead of iges or sldasm?
