Topology optimization of a lug

Altair Forum User

I have to perform a topology optimization on a simple rectangular lug as like shown in fig., only the thickness is comparatively large. I have divided the lug in to two part from centre: one is designing space and another is non-designing space. And taken stress as dconstraint. But while compiling following errors are coming:

'Stress/strain/force response is applied to topology or free-size domain for stress-constrained topology or free-size optimization,

Please use STRESS option on the design variable definition card.'

So please anyone how should I correct this error...
THANK YOU

Hi Prateek,

 

Instead of creating a Dconstr for stress, apply stress constraint on DTPL card. 

 

Goto Topology panel>>Parameters>> StressConstraint and use this to apply stress constraint.
