2D in Fluent Vs 2D in CFX
 
Hi everybody,
I want to know that does the method we use in CFX for a 2D in FLUENT?
I have solved a 2D model in CFX but it gives me floating point error in FLUENT....

As you may know, in CFX we just generate a mesh with two nodes in depth, and this will be our 2 D model....I know that FLUENT is able for 2D simulation...i just want to know that does the same model with 2 nodes-in-depth work in FLUENT or not...

if not, what do you think might be the cause of error in my case?

Thanks a lot

As you know CFX is not the 2-D solver. Therefore to run this case you should adopt any one of the following approache:

1. Use the 2-D mesh (better approach)

2. use the symmetry condition on both sides

Hi Far,
Thank you for your reply. I know that about Fluent.
My question is this:" Is a 2 node-in-depth mesh valid in FLUENT?

Regards

Yes it is valid, in this case you need to apply the symmetry on both faces.

Thanks a lot

but be careful and check solution with more nodes as well
