<div dir="ltr">Stefan,<br><br>Many thanks for your reply. I am trying to find the velocity gradients near the wall. I identified the walls of interest and have collected the element number and faces of each of them. And then approximately I try to compute du/dy, so I tried to access the velocity at the GLL points and the co-ordinates.<br>
<br>I just found that nek has a routine comp_gije(), which I believe is to compute the gradients. I now plan to use that to compute the gradients near the wall. In a earlier mail, Paul had mentioned the different ways of computing the gradients and I am looking at few of them.
