Default Viscous Drag with UDF
Posts: n/a

I am trying to compute forces on some wall, pressure forces are easily computed (i have pressure on wall & area). But i cant find anything to do with viscous drag. (and nothing on velocity gradient on the wall)

I found Compute_Force_And_Moment (domain, tf1, x_cg, f_glob, m_glob, TRUE); in f_wall.h. Any ideas about this boolean (here set to TRUE)?
