Distributed Loading

Altair Forum User

I been trying to figure out how Optistruct performs distributed loading on an object. To do so, I made a 2D rectangle and applied a force at each node on the top of the object and a constraint on each of the bottom corners. I would expect there would be material everywhere a force was applied (along the entire top of the object). However, that is not the case. I only get contact surface at a single point. Is this correct and am I applying a distributed load correctly (selecting all the nodes and applying a vector force)? A jpeg of my resutls are attached.

Thanks ahead of time,

-Dave

Perhaps you need to exclude contact area from the design space

So I made a few models with a non-design 'skin' and applied the force to that - is that what you mean?

Yes, but it does not need to be 'skin', it's just your pre-design, it can be solid

You can read in help about 'topology optimization of control arm' to create a such non-design space

No, I'm tracking. Thanks for the help.
