FEA based optimization is a powerful tool to push the design to the limit of physics. A optimization problem typically includes 3 factors: objective, design variables and design constraints. Below are some examples of them.
Objective
- Minimize weight
- Minimize the max stress
- Maximize stiffness
Design variables
- Shape
- Topology
- Lattice patterns
Design constraints
- Stress
- Dimensions
Our general workflow is to define a framework through topology optimizations and then design manufacturable geometry. The final geometry can be further tuned through free shape optimization.
