Yup, assuming you have version 15.0 or newer, check out the component system called "External Model". This system lets you attach meshes of various formats and then you can connect a mechanical...

Yup that works too... And by keeping those shells as interior, you can more easily post process on them.

Sure... The red pipe is not a problem. OGrids are the secrete here also. But first, does the red pipe inject fluid into the mixer (is it open)? Or is it really just an obstacle? It would cause a...

Assuming the symmetric shell is in a unique part name (such as "SYMM") you can turn off all the other parts and just delete the elements.

There are a bunch of element selection options, so if you...

This is most likely an issue with association between the block face and the surface.

Does the mixer move separately from the stators? I would guess so.

I suggest you add a cylinder around the mixer to separate things and treat this as two simpler blockings. Each blocking forms...

However, if your solver is able to define periodicity without periodic mesh, then you can get away without it.

"Min Angle" quality in pre-mesh is the same quality diagnostic which is used under mesh quality. It computes minimum internal angle.

Looking at the code, the "Angle" diagnostic in pre-mesh shows...

In your case, I would suggest setting a smaller size on the trailing edge and setting ortho weight to 0.5 so the prisms will lean into the corner (it looks like you have it set to 1.0)

Yea, I think the issue is that you have separate parts instead of a multi-body part.

You should select all your parts in DM and right click to form a new part... The mesher will then know to give...
