Hello,

I have been running very basic FEA on a generatively designed part in 3DExperience Simulia 'structural scenario'. Unfortunately, I do not understand why I get four very distinctive stress concentrations along the diagonal axis of the right support node, which is constrained in the vertical and out of plane directions.

I was wondering if anyone had a possible explanation or if it was likely an artefact from the BCs/inaccurate modelling of the part. It doesn't seem to be mesh related and adding material around the cylinder only seems to make it worse.

Many thanks,

Antoine
