Hi Han-yu,

1. If you want the insertion force data, add a Probe for Joint Load Reaction Force.

2. If you want the contact pressure, you can get that by inserting a Contact Tool in the Solution branch and insert Pressure.

3. Finally, there are some contact items that are not written to the output results unless you request them. You do that here:

then you have to solve again!  But you probably wanted item 1 or 2 above anyway.
