How to get data in an rigid surface in Abaqus

Recently,I made a model of two parts

1. a circle pad (deformed)

2.a discrete rigid line (move upwords)

the problem is I want to get the reaction force in the rigid surface,but I can not.

I must get it from the pad because I must make the rigid part more well meshed,I want to get better data.

Could you tell me how to get data in rigid part when contact occur?

Thanks a lot.
