In my “Piston” model the constraint boundary conditions are applied to “face sets“ as shown in the image and yet the report does not document this, I think it should. Similarly for the load cases…
Some material properties are listed including Young’s modulus & Poisson’s ratio and I think it would be good to be able a 0.2% proof stress, UTS etc.
Hope this helps.
By the way, I am very impressed.
