Hi NEKs,<br><br>I'm new to NEK and as a first exercise I'm calculating DNS of turbulent channel flow. So far everything is fine and works as is should.<br><br>Now i wanna do some postprocessing with the (binary) files I dumped out. Let's say I wanna look at a single file:<br>
<br>Is it possible to calc the 1d mean of u over the whole channel domain (for example with "call planar_average_s") then take this 1d mean profile and subtract it from u at every point to get u' (=> u'(i,j,k,e) = u(i,j,k,e) - <u>(j))?<br>
<br>As I didn't dump the averages with "avg_all()" the hint given in <a href="https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2010-May/000451.html">https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2010-May/000451.html</a> in this case is not applicable.<br>
<br>Thanks!<br>Jan Frielinghausen<br>
