How many types of goals and constraints were offered in discovery topology optimization? Can topology optimization be applied under multiple working conditions?

[Charudatta Bandgar]

Hello Frank ,

Currently, you can use optimization to either maximize the strength of your topology, minimize the response to free vibration, or both. You can also target a specified frequency or optimize to remove excess material.

The goal for your optimization. You can:

• Maximize Stiffness: This option, which maximizes stiffness and minimizes compliance, reduces the volume or mass but maintains the maximum stiffness possible for the remaining structure.
• Maximize Natural Frequency: This option minimizes the response to frequency vibration.
• Balance Stiffness and Frequency: This option attempts to both maximize stiffness and minimize the response to frequency vibration.

In constraint for your optimization. You can constrain the volume reduction (by maximum percentage/ maximum volume) or a target frequency, or both.

 

You can also optimize to Remove excess material (as your goal), and define Aggressiveness, enter a value for how aggressively the solver refines your shape.
