During each design cycle of a topology optimization study, the densities of the elements in the design space are adjusted to effectively redistribute material. Material is added where it is needed most to meet your objectives and removed where it is not required. Once the study has converged on a solution or the maximum number of cycles has been reached, you can view the results as a contour plot of relative densities. Elements with densities near zero do not contribute to the functioning of the part, while elements with densities near one are required to meet your objectives under the specified loading. You can generate a 3D shape from the finite element model by selecting the elements you want to retain. You do this by specifying an iso-contour level, which defines surfaces that form the boundary between the elements to keep and the elements to remove. Once you have generated the new shape it can be used like any other 3D shape created by a model app. | |||||||||
