We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello,

That does look like a bug in Aqwa (or Aqwa Workbench), I will log it and try to get it fixed for the next release.

As a workaround, you could alternatively use the Python user-defined force function to apply your time-varying loads to each structure. The Aqwa solver can be connected to a Python server (code is provided in the installation) so that a Python function is called at every time step. Please see the Aqwa Reference Manual for more info: 30.3. External Server for User-Defined Force Calculation (ansys.com)

Please let me know if you have any problems or questions.

Mike
