Compression of a spring using Rigid plate

Altair Forum User

HI all,

 

I am an ABAQUS user and a newbie to Optistruct. I am simulating a simple spring compression simulation and have a few queries. 

1) What is the element type to be assigned for the 2D - rigid plate to be used ?

2) In ABAQUS, no material property definition is needed for rigid. Is it the same in Optistruct ?

3) For the spring, I have used CPENTA for penta6 and CHEXA for hex8 elements. Is it correct ?

4) What is the equivalent to R3D4 of ABAQUS in Optistruct?

 

Thanks in advance for your help.

Rigid plate you can define via RBE2 element.

In optistruct also no material property is needed for Rigid which have infinite stiffness.

Springsyou can modelled via bush elements.

R3D4 is for CQUAD4 element.
