Simulation results differences

Hi all,

Actually working on a topology optimization project. I performed a first simulation of an assembly using the Structural Scenario Creation app. After analyzing the results, I performed the same simulation on Functional Generative Design app. Problem : the Von Mises stress are approximately 10 times bigger in this second simulation (despite using the same assembly, loads, mesh, etc.). In my opinion, theses discrepancies in results are due to different calculation algorithms, because the apps are different. So, here are my questions, which results should I consider ? Do you have any idea of what could have gone wrong ?
