Ensuring that Structure of Topology Optimization is connected to NonDesignSpace

Recommended Posts



I have a problem using Inspire. I am doing a topology optimization of an upright.

The problem is that the structure which the solver outputs to me is not connected to all of my non design space.

The bearing at the bottom of this picture needs to be connected to both of the cylinders but is only connected to the top one.
I alrady tried to separate the bearing (1 constraint and the other 2 contraints) but that does not make any sence at all.

I also saw a picture, where it worked with nearly the same connectors.

The only difference was that the forces were not in the center of wheel but in tire contact patch.


I already tried this, but it does not work for me.



Thank you.

Hi, I've been having a similar problem.

I'm making a big disclaimer first: I'm kind of a newbie with the software, so don't get what I say as sure.

Btw, I kind of worked out that Inspire does that when it thinks it's impossible to match volume reduction and stiffnes/safety factor requests.

I'd suggest to try an higer percentage of starting volume (for a stiffness opt.) and see if that works.

Hope it can be helpful
