ANSYS12 - named selections not transferred
Hello there,
I've got an issue here I can't get solved. Surely something very simple I just don't happen to know. In the workbench, I use DM to create a geometry, in the geometry I create named selections. The second module in the workbench is "Fluid Flow (FLUENT)". The issue is that the geometry is imported when I start AM (the mesher), but none of my named selections show up.

Anyone out there who knows how to solve this?

Thanks heaps!

Ansys has no answer either... highly unusual... I'll just create the named selections in AM from now on...

workbench-->tools-->options, Geometry import, you can find something to activate the Name selection transfer.

I tried this, without any success! The Ansys support guys said everything was done the proper way, but they didn't have an answer as to why the named selections wouldn't appear in AM!

Ha! There is a solution:

To make the named selections created in DesignModeler available in the mesher you need to enable named selection transfer. Click on Geometry in the Fluid Flow analysis system and click on the Named Selections box under Basic Geometry Options. This will automatically enable the NS filter next to Named Selection Key which will only allow the transfer of named selections with "NS" at the beginning of the name. You can either rename your named selections in DesignModeler to include "NS" or clear the field as I have done below to allow all named selections to be passed to the mesher. Refresh the Mesh branch of Fluid Flow to complete.

That's great! Thank you for share this.

Ey!!! Did it work??

The easier thing to do is to create the Named Selections in the mesher and not in DM. But don't forget to allow the NS to be transferred.

Then you'll have your NS in Fluent or I hope so, lol.

Yeah, all works fine!

That's right, the named selections are easier to create in the mesher, the reason why I need this option is that I create the named selection in the CAD model. Now, they are passed all the way through!
