Additive Manufacturing Constraints in Topology Optimisation

Hi,

 

Is there anyway to integrate Additive Manufacturing constraints for topology optimization in optistruct?

 

I would like to add constraints such as maximum overhang angle, minimum number of support structure, etc...

I would also like to determine the best build direction.

 

Thank you

    Hi @Intan

     

    Overahng is a completely new feature and not available through GUI. But you can add the constraint to the solver deck via DTPL card. 

     

    Please refer to OptiStruct user guide for more information.

    Hi @Prakash Pagadala

     

    I'm integrating the overhang constraint in my design variable for the topological optimization. However there are certain fields that I don't quite understand the definition.

    For one, from the guide, the Point Selection 1 and 2 define the grid point identification numbers which identify the orientation. What orientation does it refer to? Is it the built orientation?

     

    Thank you and regards,

    Intan
