Hi all,


I have 3 plates of .016" thickness stacked one over another, fixed at the bottom (fig 1) and pressure(15 psi) is applied on the top face(fig 2), and no penetration contacts with COF of 0.1. Since it a very thin plate,i am using non linear analysis because the plate exhibit geometric non linearity and cannot be run in linear study. Also i have used solid mesh as i require the solid deformed model after the analysis in solidworks 2012 sp 5.


Number of elements: 31,000

Number of nodes:  64,000

Degree of freedom: 180,000

Solver used: Direct sparse.


My system configuration and model in consideration are as shown below. Please suggest on how i can speed up solving time.









Thanks in advance
