CFD Online beeing upgraded??

acasas · May 10, 2013, 08:23

hi guys!
I must say this CFD Online forum is great, well, the best. However I´m doing FSI analysis and I´m not able to find a GOOD ansys workbench/mechanical forum on the web. Any suggestion?
From my point of view, I really think that this CFD Online forum should be upgraded to something bigger, lets say FEA Online, or so? Wouldn´t be great??!
I´m sure lots of users are interested in FSI discipline and need suggestions, inputs, comments, help, etc from several disciplines, like fluid, thermal, mechanical, etc.
Hope that with users and administrators help, this can be accomplished.
Thank´s

There are websites for FEA however...

Hey Lefteris,

could you suggest me a good FEA forum website?

I don´t know how to add a convergence method on a FSI problem. A pressure solution from CFX fluid analisis is beeing aplyied over a wing shaped structure as a load. When I try to add the convergence method under solution options in mechanical workbench, this option is not availabe.
If I do supress the imported pressure, and add a simple force load on the tip of the wing shaped structure, then, YES, this option is available and I can use this convergence method.
Maybe you can help me?
thank´s

I know there are a bunch of ANSYS groups on Linked In. Some are regional, others are based around products like ANSYS Mechanical. Start asking there... Maybe you can get help on linked in or maybe they can point you to a more FEA centric site...

If you can't find one, perhaps it is time for someone (maybe you) to start FEA-Online.com

This was the advice from Ferit Boysan more than 10 years ago... but we have tried to stay CFD focused. We have the http://www.cae-online.com and http://www.fem-online.com domains though. Perhaps a first thing to try could be to open a FEM sub-forum here.

Yes Simon, so far, Linked in seems a good advise. Thank´s.
Regarding starting myself a FEA Online.com, unfortunately I don´t have the knowledge enough to do it, and even the time for it, but maybe one day when retired it´s a good option.

Jonas, I did try to open both websites you suggested and none of it works

. Still, thank´s for your answer. I do agree with you, maybe you guys could open a FEM sub-forum here?

Several people have asked us before to open forums related to structural analysis. We have decided to finally give it a try. We just now opened the following forums:

We will see if these new forums work our. You can try posting your questions about FEA in the new structural mechanics forum.

thanks´a lot Jonas!

I´m happy. I may now be able to get some help over my FSI and Ansys mechanical problems.

Not sure I´m allowed to say in this forum, but...
I have a Volvo 123 GT, made in Gothenburg, form the 60´s.... Now I understand why it works so well
