optimize a single point constraint to withstand forces

Altair Forum User

Hi,

 

I am a new HyperWorks user and I’m trying to setup an topology optimization.

 

As optimization constraint, I want to declare a maximum force on my SPC’s, but I don’t know how.

 

The SPC’s I’m using are respectively bolted holes. I have defined them with RBE2 Elements with a calculated node in the middle of the hole.

In the post-processor I already can see the forces on these SPC’s.

Is it possible to define these forces with a maximum value in the pre-processor? How can I optimize these SPC's forces to an maximum value of force they can withstand?

 

Thank your beforehand for your answer.

You must first create the necessary response, in this case it is the Single Point Force at a constrained grid point

 

This response can be defined using the DRESP1 bulk data entry (with RTYPE=SPCFORCE).
