This tutorial demonstrates how to perform topology optimization using pattern repetition. The model is a rectangular plate with a concentrated force on one edge and two constraints on the opposite edge. Two other rectangular plates with a scaled size of 0. The objective is to minimize the compliance for the single subcase. The volume fraction of the design space is limited to 0.

The design spaces are the three plates. User Profiles… can also be accessed from the Preferences pull-down menu on foletype toolbar.

An Import tab is added to your tab menu. Setting up the optimization problem without pattern repetition.

Create the Volume Fraction and Compliance Response. Create a Constraint on Volume Fraction Response. This creates the compliance response as the objective. This completes the definition of the topology optimization problem without pattern repetition. Post-processing the results without pattern repetition. An isosurface plot is displayed in the graphics window. Note the display of each plate. Those elements of the model with a density greater hyperworka the value of 0.

The pattern repetition cards can now be defined in HyperMesh. The second component is scaled 0. Post-processing new results with pattern repetition. A Message Log window will appear, indicating the location of the. An iso surface plot is displayed in the graphics window.
