How to calculate deformation and Force in COMSOL Multiphysics with a hyperelastic compression configuration?

I was able to use prescribed displacement to solve the configuration but I need to calculate the Force for each deformation.

Define a Nonlocal Coupling integration over your hyperelastic domain. Under the advanced settings for this coupling, choose "Summation over nodes".

Update your solution.

In your results, you can plot "intop1(solid.RFz)" for your auxilliary sweep, (if you want to see the reaction force in the z direction).

Hi Mark,

Here is the 2D.mph file for the simulation, I tried what you described but i am not getting the steps. If you can help me to look at the file.

Will the same steps work for the 3D as well?
