Support position

Serge Mrad

Hi, I am modeling a structural steel connection, and I would like to perform a topology optimization with maximizing stiffness.
Kindly, I would like to ask if someone can guide me on where to insert the support, as the result is highly affected by the support location. I attached an image of the original connection.
Thank you for your help in advance.

what are you trying to optimize?

The middle green area?

It would be nice to have more details about what exactly you are trying to accomplish.

if you know the load for each truss, you can try to apply all of them, and run an inertia relief analysis, with no support. IR will calculate the resultant load and try to compensate it to avoid rigid body movements.

But I would take take with the rotations at the joints, and how to model the connection points, and also what areas are designable or not.
