Hello everyone,

I am trying to export a problem that was set up in Live to Fluent, in order to solve it.

My idea is to play with some different parameters on Live, see which is my best combination and then export that combination to Fluent and solve it in a proper way.

When I do that, Live only transfer solids, but not faces (which are some of the modifications I did in Live).

In addition, boundary conditions set in Live are not transfered to Fluent neither.

How should I transfer this to get the same problem that I made in Live to Fluent.

Thanks

Hello DanHeHe

The model that you shared doesn't contain any surface bodies. I quickly copied one of the faces to create a surface body and then exported the model using Workbench - Fluent 2020R1 - Export PMDB. The exported PMDB file had both solid and surface bodies.

Boundary conditions are not transferred from Live to Fluent, only geometry is transferred.

Thanks for your reply Naresh,

but I do not understand why should I create a surface body to separate a face in two different faces. As I did it, I had just one volume, but I could include faces where I wanted to generate different boundary conditions.

Why these faces are not transfered to fluent?

Thanks

Hello DanHeHe

There is no need to create a surface to separate a face in 2 different faces. If you select the underlying face, switch to sketch mode and create a closed sketch (like a rectangle), switching back to 3D mode will separate the sketch region as a seperate face from the underlying face. There won't be a new surface body created. 

Regarding the imprinted faces not getting transferred to fluent, for that you need to create Named Selection for the imprinted faces. Select the face, then go to "Manage Groups" panel and select "Create NS". See below snapshot.
