Transient 3D loading of contact pairs

I am currently working on modeling a ball and joint interaction in comsol in 3D. I have currently set up the analysis and set up a contact pair between the surface of the ball and the surface of the cup. I am hodling the fall stationary and allowing the cup to move freely as I apply a load to it. However, I cannot generate an analysis which converges.
Here are things I need answers or help with:
1) How can I apply a load over a time span. Persay, apply 100 MPa in a time of 5 seconds?
2) Accomplishing this transient analysis, how can I get the solution to converge given contact of the two surfaces?
If someone would be so kind as to answer in simple terms and break everything down for me as I am fairly new to comsol multiphysics.
Thank you,
John
