Assuming this is all quasi static, then use linear static, and instead of a force (remove it) use an enforced displacement on top to press down the upper plate.


To see the force just use a force reaction probe. From there you can read of and see what kind of deformation one gets at 150 kN.


Finally increment the enforced displacement using sub-steps say (10 -1000 depending on how much disp. you apply)
