Good Morning,I want to Model a bearing support instead of consider a actual bearing geometry and then meshing it.Here I attached my model and mark the bearing region in blue ink.Thanks & regards ,Sivaprakash. V
Yes, I tried two ways.CASE 1) Using By face option, select the nodes by face only which bearing face is connected with shaft. Then Create a RBE 2 Element, In rbe 2 dialogue box I fixed all the DOF of Dependent Node ( master node or center Node). Then Creating One load collector and apply Spc ( Dof 6 is free all others are fixed).CASE 2) Select all nodes in bearing Location by using Box select option, Then create the Rbe 2 element and Repeat the case1 for apply constraint.I Request you to tell me which method is correct or share any model if available .
Case1 is fine for the scenario you have explained.
Thanks

Hi Siva,
It is difficult to understand what you want to model.
Can you elaborate more on this?
Hi Rajashri,Thankyou for reply.The above shaft Model which contains two bearings. The Bearing locations are mentioned by the arrow mark ( Blue). I meshed the shaft model, Now I want to create a constraint similar to actual bearing condition. I didn't want to mesh the bearing and I want to give actual Bearing work by applying constraints.Thanks & Regards,Sivaprakash V.
If you want to put constraints directly to the shaft, you can do it by creating SPCs which represent constraints in optistruct. You can select the desired dofs to fix.
Thankyou !
