Topology Optimization: Error # 312

Recommended Posts

Hello, I have been trying to make an optimization of a hardpoint. I want to optimize the weight under load applied in grey zone

I have introduced all the parameters of the optimization (Response, Constraint, Objective and design variable). But the following error appears when I run the simulation:

 

*** ERROR # 312 ***
 In static load case 1 
 the compliance is negative or large -1.96593e+012.
 Optimization/buckling analysis cannot be performed.
 due to possible rigid body mode.
 FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED).

 

 Could you help me with this error please, and also could you verify if the 3d model is correct, or I have to make only one volume?

 

I attach the hm file as well

 

Than you in advance

This error occurs when a model is under constrained or incorrect material property definition or contact definitions are incorrect or missing.I see there is no connectivity between nondesign and hardpoint component.Equivalencing nodes should help to run the optimization.

I have made a equivalence and the simulation runs correctly. Thank you

 

It is mandatory to separate in two design spaces? Or it is possible to perform only with one volume?
