Detailed Description

Compute the integral of viscous force that the fluid exerts on a surface, or \(\int_\Gamma -2\mu e_{ij}n_jd\Gamma\), where $n_i$ is either the $x$/$y$/$z$ direction (or the magnitude of the entire force, if the component is 'total').

Note that this calculation is done directly on the mesh that nekRS solves on, not the mesh created for solution transfer in NekRSMesh.
