Hi folks, im new here and im also new at using CREO Simulate, havent really gotten the grabs of this p-element stuff yet.
To the point: I'm performing a static analysis of a lifting lug which is affected by a force acting on a surface inside a hole, this surface models the contact surface between the hole and the lifting tool. The lifting lug is constrained by bolts in holes and i've also constrained it to only move planar for a specified surface (see picture i attached).
I set the solver to MPA where i seartch for convergence of strain energy, von mises and maximal principal stress for the whole model. I set a convergence criteria to 7%.
The current mesh setup allows the solver to find a solution within the specified convergence criteria.. BUT in the "Run status report", in the last pass, it also stated that there are X-number of elements not converged..

The result give me both von mises and max principal stresses that are WAY above the value it should be. The area of interest is the bend and the hole section, stresses at the bolt holes are not of interest. The model material is S55, ive set modulus to 190 000 MPa and poisson to 0.3.
Does anyone have a any tip or tricks to get more accurate stresses? I've also attached the .prt file so that you can try the simulation yourself.
Cheers
