Plane axisymmetric elements

Altair Forum User

Hello,

 

I'd like to perform a plane analysis of a rotor component. Usually in ansys I used to use Plane182 elements.

 

PLANE182 is used for 2-D modeling of solid structures. The element can be used either as a plane element (plane stress or plane strain) or as an axisymmetric element. The element is defined by four nodes having two degrees of freedom at each node: translations in the nodal x and y directions. The element has plasticity, stress stiffening, large deflection, and large strain capabilities.

 

Is there any corresponding element type for Optistruct? I tried to find it in the user help and tutorials but I wasn't successfull. I'd appreciate your help.

 

Best regards

Jakub

Hi Jakub,

 

 

Can you check with CTAXI with PAXI property referenced?

 

 

You can get more information about these on OptiStruct help.

Hi Prakash,

 

could you correct me if I'm wrong?

Does it mean that hyperworks does not support axisymmetric quad elements like cquadx4 or cquadx8?

I found description of CTAXI and CTRIAX6 but no other elements are listed in solver help.

Is there any tutorial how to introduce CTRIAX6/CTAXI on my own as the elements can not be picked from a list. (so far the only description is available here)

I use HyperWorks v13 with the latest updates and such situation is slightly disappointing.

Hi Jakub,

 

OptiStruct can work only with CTRIAX6 and CTAXI for now.
