channel flow-velocity in the wall

Hi all.
I am modelling a channel where the bottom consists of many triangles equally spaced. I have already a solution. When I plot a velocity vector the profile seems correct because there`s no velocity in the bottom (using hybrid values). However, when I export a .dat profile (using hybrid or conservative) the velocity in the wall (y=0) is not zero. In the documentation it says that for quantitative calculations one should use conservative values. My objective is to do a spatial average of several velocity profiles along the channel. What is the best option/way for this objective?Using conservative values and consider the first point where y=0 (with u different from zero) garbage? A light would be very helpful. Many thanks |
