Simple Topo but no convergence - whats wrong?

Recommended Posts

Hi,

i have done a simple Topo. Unfortunately, the result is poor. no convergence.

 

-objective function: minimize mass

-constraints:
static displacement x < 0,5
static displacement y < 1

-mindim: 15

important to me is to achieve the displacement constraints as closely as possible.


But look at the screenshots, something is wrong. But where is the error?

 


Thanks for your help,

Please increase no of iteration using Opti control. See attached screenshot & refer Optistruct user guide

Limit has reached and also constraints are violated.. Let some more iterations run on this one & check.
