Hello everyone, during preparation for a project I used the course "CATIA Functional Generative Design Essentials" in the "Edu SPACE" to get used to the FGD App. Following the course's example "joiner" I got to the step "concept generation" after the topology optimization. If I hit the button "Generate" in the concept generation dialog box the attached message is shown. The buttons "Finish" and "Discard" ends the operation and "Generate more concepts" leads me back to the dialog box of "concept generation".

I tried a topology optimization with different models, but it all led to the descripted problem.

Does anyone have a clue? Thanks in advance.
