[ICEM] Blocking technique for models with small number of faces

badboyz31 · March 27, 2014, 02:48

It's been a while now, and I seems to have identified my problem in ICEM blocking.

Usually I have to associate a block (8 vertices, 12 edges, and 6 faces) to the model. However, how should I associate the block to a model with fewer geometrical elements ?

I've tried to reduce the number of vertices by merging them, but it ended up with an invalid face error in CFX.

The picture of my model is attached. The surfaces are created with simple surface method.

I've been looking for tutorials, but nothing comes close. Any help is appreciated.Thanks in advance to everyone at CFD Online.

I've also tried to use "Collapse Blocks", but the same invalid face error keeps recurring.

I am in need of help here.

You can try to use wedge blocks for this. For how to create these I once again reference Simon's tips and tricks (from page 93 on). It might be a little tricky but it should be doable with 3 of these wedge type blocks.

Actually I followed page 99 (airfoil). Well I'll try it and see what happens. Thanks mate.
