CFX Build 5 question...

cfd guy

Hi everyone...

I've been using CFX-4 for simulations, but recently we acquired the CFX-5 package here at the university for researches, so I'm a new user in this code.

And I would like to know from you about the meshing aspects. Since we want to solve unstructured meshes in CFX-5, we must know how to generate the grid files for it. In BUILD 4, it is suggested to create as many blocks as your geometry requires, for avoiding future problems in convergence, etc... But in the BUILD 5, almost all tutorials examples works with one simple block (a B-REP Solid), generated by several surfaces. Why that?
Is there some recommendation to avoid create multi-blocking, as I use to work with Build 4? I was trying to generate a multi-block grid in Build 5, but it failed when I tried to set up a interior wall (Thin surface) in the domain. I searched the manual and I found out how to create thin walls, but it seems that doesn't work with multi-blocks, since I must take care with domains and sub-domains fluids, which I suspect that I created them correctly. So, if anybody could supply me a hint, I'd be very thankful...
Regards!
