Constraints in HyperMesh

Altair Forum User

Hey guys!

 

I would like to do a linear thermal analysis. I would like to catch the proper behavior of my system that's why I used constraints in the thickness direction of a thick aluminium plate.

The plate should dilate in all direction but the top side of it.
 

How can I apply such constraint which allows the displacement of a node in the positive direction of an axis and obstructs the DoF in the negative direction?

Should I use some kind of contact for this purpose?

 

Thank you for your time and your answer in advance!

 

Kind regards,

Imre

Yes, use contact.
