Optimize cross section material beam

I want to optimize a beam, this is not a problem with the different steel profiles, but if I change the material from S235 to S355, nothing changes.

Hi, I think you have used the optimise cross section component incorrectly. You need to first assign one cross section to the beam, and then plug in the family of cross sections to use for the optimisation. Please see the images below. Once I change the material to S355, you see the beam profile changes.
