Femap as pre-/post for Inventor Nastran to use "brick" elements?

Hi all,

Is it possible to use Femap as a pre-/postprocessor for the Inventor Nastran solver - through the Inventor Nastran editor? - to use the CHEXA "brick" element definition that is in the Inventor Nastran solver reference guide? 

(in other words: can Femap be the work around needed for as long as Inventor Nastran in itself fails to support the "brick" elements asked for in idea-station since 2015? - Allow 3D brick elements - Autodesk Community)

We would like to be able to use 20 node hex elements in situations where tets prove to react to stiff. 

Regards,

Jaap

Hi @jaap_vander_heide,

 

Yes, FEMAP can and is used by others as a pre/post processor for Inventor Nastran. FEMAP does have the ability to write out most setups to a deck file that works with Autodesk Nastran.  I know there is a couple of things that don't work right, but they aren't common things, so I can't remember what they are at the moment.

 

And yes, you should be able to use the CHEXA "brick" element.

 

Thanks,

James

I want to add that recently Femap added a near bullet proof hex dominant mesher.  I have been playing with it quite a bit.  While it's slower, it's very robust and does a great job around small features.  Please message me if you want more info.

I have just been watching the AU 2024 presentation about this and I must say it looks pretty promising. :smiling_face_with_smiling_eyes:
