Why is my Shape growing?

• When you recognize that your optimisation result is growing in an inappropriate way - something is going wrong

• The main reason for this is the tearing off and therefore lost connections of the Nondesign spaces to the Design space on which the structural loads are applied

  • In these iterations there are 0 MPa stresses (see picture below)

Open

• In the following iterations the model is arbitrarily growing again

• If a connection between the Nondesign space and the Design space is created anew, a stress will appear again and the optimisation will go on considering all conditions and constraints applied

Steps to prevent this behaviour:

• The occurring stress doesn’t fit to the optimisation goal

  • Lower the stress goal of the optimisation

  • Increase the applied structural loads

• The resolution is too coarse

  • Increase the Complexity for a higher resolution

  • Change Strut Density from Sparse to Balanced or Dense

  • Use the Advanced User Settings to start at a higher resolution
