Hello,

  1. In this video at time 16:30, you should see a demo of how to obtain Contact Force Reaction: Understanding Basics of Contact - Lesson 2 - ANSYS Innovation Courses
  2. With regards to why you are getting contact reaction forces much higher than the applied external force: to interpret these forces, you would need to draw a free body diagram for each individual part (since these contact forces are forces that one part exerts on the other and vice-versa). The forces on each individual part should balance out. Another thing you need to keep in mind while drawing these free body diagrams is that the applied remote force also generates a moment. Watch this video from around time 16:30 to understand how the free body diagram needs to be considered for each individual part: Utilizing Remote Points Properly - Lesson 4 - ANSYS Innovation Courses

Hope this helps.
