Thanks. Sorry for all the questions but how do you actually check for folded elements in ICEM?


I've looked at the determinants, angles, warpage. I have some very small 2x2x2 determinats (of...

So I've imported the mesh into CFX without any errors and set the inlet, outlet and wall BCs. Then I applied symmetry boundary conditions to the two side faces (they are in individual parts this...

Apologies to neewbie and all the other folks (I seem to be a bit slow last few days). I over looked the options and I do actually have Ansys CFX in the Output options and I can load it in now without...

Manually deleting Zone 12 in the *.msh file doesn't work. Still gives the same error.

Great! Thanks neewbie.

I found that Zone 12 (in the *.msh file) was actually referring to the 3D Blocking created in ICEM (which is indeed an internal region).

You'd think that CFX will realise...

Cheers for the reply neewbie.

I think the problem with the mesh in my first post was because I saved the two sidewalls in the same part in ICEM and tried to apply symmetric BCs on it. I was being...

To neewbie

Sorry, I don't understand what you mean by setting the output solver on Ansys-CFX. I create the mesh in ICEM and when I select the output solvers I can't see Ansys-CFX. The only CFX...

Hi Glenn,

Thanks for the post. That was actually really useful.

1) I understand the difference between the two now. I have to use symmetry BCs since it needs to be 2-D. What I am really...

I guess the first thing to check will be to make sure that there's nothing wrong with the way the mesh is saved in ICEM.

So I created a very simple rectangular block without any rotational axis (I...

Thanks for the reply. I've tried to set periodic boundary conditions now.

Earlier the two sidewalls of the mesh were in a single part (created in ICEM). I assumed that for periodic boundary...

I guess I should have define the problem clearly.


My question is how will I set the boundary conditions for my mesh. I'm only considering the upper half of the geometry for a 10 degree angle...

symmetry boundary conditions in cfx

Hi,

I'm trying to study the flow through a converging-diverging duct using CFX.

Since the problem is axisymmetric I'm only consider the top half of the duct and using 10 degree angle segment.
