[ICEM] meshing issues in ICEM CFD

acjoshi · April 5, 2012, 00:44

Hello,
I need some help with meshing in ICEM. I have been using GAMBIT all this while but felt the need to speed up my meshing and hence the move to ICEM.

I am trying to mesh a very simple problem with a porous zone.

So the domain consists 1 fluid zone separated by a porous zone.

I am able to create different material points hence hence Cell zones in Fluent.
Domain size 600x800x800mm
I have a porous zone at X = 200 which is 100 wide

I created 2 fluid material points one on each side of the porous zone and assigned the split blocks to it. Assigned the middle block to the Porous zone.

Defined the porous walls as interfaces.

However when I mesh the geometry my 100 mm wide zone has only one cell. The moment I remove the definition of the interface walls the mesh appears correctly.
Can anyone help me with this?

It may be the problem of association. Attaching some figures to show your problem may help to find the root cause.

I have meshed this exact problem except with different dimensions in ICEM. Sounds like it could be an issue in your "part mesh setup". What do the parameters look like for the porous zone and the associated surfaces?

Whether you are correct in defining the "create body"?
