Topological Optimization

• Algorithm;
• Realization Method in CAE Fidesys.

Algorithm

Topological optimization is a type of analysis, the result of which will be the appearance of a structure that has the strength properties of the original structure (or design area), with the lowest possible mass.

The general view of the block diagram of the method for topological optimization of structural elements is shown in the figure below.

Method realization in CAE Fidesys

Important: only single-block models are supported for this type of analysis.

In order to use this type of analysis:

• build an initial structure or design area;
• build a finite element mesh;
• set properties of elements and material;
• set boundary conditions and loads.

Then start this type of analysis from: Mode — Calculation Settings, Calculation Settings — Topological Optimization.

The final result in the FidesysViewer after applying the Threshold filter will look like this.

You can also look at step-by-step example of topological optimization of a loaded body with subsequent 3D printing

More details about the topological optimization algorithm used in CAE Fidesys can be found in [1].
