The non-ortho stress term at boundaries is negligible, we skip it usually.

Hi, I have a question about assembing stress term in uFVM. When we assemble stress term at interior face,we need to add non-orthogonal part and velocity gradient transpose part to FluxVf, which is as followed: % Non-orthogonal part local_FluxVf = - mu_f.dot(UGrad_f(:,:,iComponent)',Tf')'; % Add transpose term local_FluxVf = local_FluxVf + mu_f.dot(tUGrad_f(:,:,iComponent)',Sf')';
But we didn't do the same thing at boundary: % non-linear fluxes local_FluxVb = zeros(size(local_FluxFb)); Why?

How about velocity gradient transpose part at boundary?
Also not of a significant order

Got it, thanks

Why?
