    Force reactions can be done in DPF with a number of methods. There are at least two main methods of calculating the total forces across a contact:
    1. Pressure*Area of all contact elements
    2. Element nodal forces of the underlaying solid elements (FSUM in APDL)

    DPF has the capability to extract all of this data and provides the operators for summation, rotation to local systems, or orientation to element-specific normal/tangential contributions.
