It's a bit too complicated to fully describe in an on-line forum, but the basic process is to create 2 grids; 1 for the blades and one for the tank. These 2 grids are imported into Build and a MFR (Multiple Frame of Reference) analysis is set up in the domains form. I think this was available in 5.5? Refer to MFR in the help menu for more details.

For that matter 5.5 is about 3 years out of date (5.7 is the current release) and I'm surprissed that your Build license still works. I would suggest contacing tech support but I'm pretty sure 5.5 is no longer supported.

It's been a couple of years, but if I remember right and you're creating the grids in Build then you need to start each database as "meshing only" mode (in the initialization panel) to create the 2 grids. Once they are done you create a 3rd database (I can't remember what mode options are available, but if there's something that refers to no meshing, or import grids then that's what you want) and import the 2 grids.

Hope that this helps.
