Sorry I mean comparing convergence between hex20 and linear. Yes, with the plate it is diverging, unfortunately.
Thanks for the force distribution advice, much better.
VMH,
Thanks for pointing out this. I was not refining enough with linear. I've tried quadratic on my side and I realize that much less refinement was necessary to reach the converging result.
Curiously the hand formula for sandwich beam gave me a s…
Thanks !
Indeed I'm working on a telescope building.
I was comparing with result of this model (end of page)

He compare result with a formula and FEM model. In MecWay I got the same result if I'm…
