Hi everyone,
I want to apply and external force
f_i
to analize compressible channel flow. As shown in the figure above,f_i
depends on the viscous stress tensorτ_12
at the wallsy=H
andy=-H
.I can extract velocities at the cell closest to the wall using
Farrs[nbx](i, j, k, URHO)
andFarrs[nbx](i, j, k, RHO)
by setting j to the cell number nearest to the wall. However, I am uncertain about the formulation of the gradients.Do you have any sugestion on how to obtain this information using the following this: https://github.com/baperry2/PeleC/blob/54c8253eb53e887d45cf436d26dbb6d549d8de53/Exec/RegTests/EB-Vane/prob.H#L125
