Complicated geometry blocking strategy
2 Attachment(s)

I have a not so straightforward domain for which I have to do a structured mesh. I had usually dealt with 2-D domains till now, so now this one is confusing me.

Here is how it looks in ICEM

I would appreciate if you guys can share any suggestions about the blocking strategy.

P.S. If structured mesh generation for complicated geometries has already been discussed in the forum at some time kindly let me know. Maybe I am not selecting the right keywords

It is really tough actually. I did a spiral blood pump once, but that was with years of experience and some trickery... and it had a simpler round perimeter so I could twist things more easily.

I would not try this one with structured hexa. Solvers are good enough that it is probably not worth the hassle. I highly recommend you try an unstructured method such as tetra prism or cutcel, you can put a finer mesh (to make up for the lack of hexa) and let the solver do the harder work.
