Hello, I am solving a similar problem. What I do is to sum the contributions from all the processors, and then use Utilities::MPI::Sum() to get the overall force which I then write in a file on a master process,
For the contribution of a single cell, you have to integrate stress X normal X area for each locally owned cell on faces on the boundary.
