Description
In Generative Design, you can now define the desired minimum feature size of the resulting geometry that controls the optimization thickness.
The new Minimum Feature Size geometry constraint allows you to set the minimum feature size for each design criteria in the units of your choice. The preferred value for the minimum feature size is 3 times the element size, with no upper limit.
The minimum feature size is listed under the Additional Information for the design criteria node in the Generative Tree.
Previously, you could not control the minimum thickness of the optimized shape. This resulted in situations where very thin features were created in the resulting model, which could be difficult to manufacture or result in the areas of weakness.
Benefits
This enhancement allows you to define the minimum feature size for optimization to capture your design intent. It controls the thickness of the resulting geometry and avoids thin-walled structures in the optimization.
