Detailed Description

Compute the integral of pressure over a surface, multiplied by the dot product of the surface unit normal \(\hat{n}\) with a user-specified direction, \(\hat{d}\), or \(\int_\Gamma -P\hat{n}\cdot\hat{d}d\Gamma\), where \(\Gamma\) is the boundary.

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