Detailed Description

Computes viscous stress at surface.

Stress is returned as a vector (i.e. the viscous force on the surface per unit area). For a steady flow with a no-slip BC, this is the shear stress. For an unsteady flow or a slip BC, there may be normal stresses.

Attention

The stress is obtained by reading the flux storage of the Boundary_connection object, which is written by the Spatial::Local kernel. Thus this only works if at least 1 iteration has been run in order to compute viscous fluxes.
