ICEM CFD 5.0 (Tetra) - Internal Wall/Thin Surface
 

Hi guys,

After working out how to do thin surfaces in Hexa, I now need to work out how to do the same in Tetra!

Do i just create thin surface parts and assign them as thin surfaces under the global mesh menu.

I basically want the model a square box with a grill (made up of thin strips) splitting the box in half.

If you have a surface which is effectively floating within a closed surface region how doesTetra cope?

Regards

James

I've done it, and yes it works easily. IIRC I just set it to a thin surface under the global mesh menu. But after the grid has been generated I think you still need to split the face (under grid edit menu).

would you give a detailed steps to do it.

now I am facing with the problem, I want to set a thin surface wall in model, but I cannot do it in TETRA. When I import it into cfx5, there is not the thin surface, How to fix it?

thanks lots!

Hi Leo,

Do not know whether u have already got your solution. N'way here goes my solution.

The thin wall thing works in the ICEM tetra provided it should be treated seperately from the other geometry in the model. Create the walls as seperate entity from the ones that are not "thin". You have to define that as a different family seperate from any other walls which are not "thin".

While meshing, in the "mesh params", for "all families", you will have to switch ON the toggle for "int wall". Then continue with meshing. This would show you the thin wall in CFX5 hopefully.:) Then in CFX5 I am sure you would know, enable "create thin surface partner". CFX thus takes the other side of the thin wall automatically and defines it as wall.

Hope this helps you! ciao
