[ANSYS Meshing] Extruding 2D mesh to 3D mesh in ANSYS meshing

Rachit · February 6, 2012, 10:01

Hi everyone,

I have been working on a 2D flow over an airfoil in fluent. I had generated the mesh in ANSYS meshing tool. It was an unstructured quad dominant mesh. Now, I have been told to extend the problem in 3D by extruding the same surface mesh in the z direction to convert it into an volume mesh. How could this be accomplished? I know a surface mesh can be extruded in ICEM CFD, but I have been told to do it for the same mesh, so it has to be done in ANSYS meshing only.

Thanks in advance!

Regards,
Rachit

Has anyone come up with a solution to this issue? I am having the exact same problem. I can figure out how to extrude a 2D mesh in ICEM to 3D quite well, but how can I do this in Ansys Meshing? Thanks!

i´ve managed to do so by creating a swept mesh,and set the source and target face manually. this means you have to redo ALL your meshing steps at the source face ... so maybe this isn´t what you were looking for.

Hello,
I guess you have created a sheet/surface model for your analysis. When in the meshing application expand the geometry tree node.. go to the body of interest, now in the details view of that body there must be a field of thickness. give whatever you want.
Thanks,
Sarang

Apparently, a surface can be meshed, a thickness specified and a 2D analysis performed. I'm only missing the possibilty of setting inflations...

But I found it's possible to right-click on the meshing method, the select 'inflate this method' to select edges.

can you please elaborate the steps?

Have you seen the dates?

yes, any link with dates and new learners to ask. If you can elaborate then ok otherwise keep quiet please.

It is a matter of managing expectations.
Better start a new query with a well written up-to-date question than to expect people are still there after 12 years. Also, the software has changed significantly since then, so possibly they have a solution that doesn't work for you.

okay, thank you
