Hi Daniel,
<div class=""><br class="">
</div>
<div class="">you want to use the ‘ifield’ index that is 1 for velocity field and 2 for temperature field. Your usrbc subroutine would look like:</div>
<div class=""><br class="">
</div>
<div class="">
<div class=""> if (ifield.eq.1) then</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>YOUR BC FOR VELOCITY</div>
<div class=""> else</div>
<div class=""><span class="Apple-tab-span" style="white-space: pre;"></span>YOUR BC FOR TEMPERATURE</div>
<div class=""> endif</div>
</div>
<div class=""><br class="">
</div>
<div class="">if you only solve for velocity and temperature fields.</div>
<div class=""><br class="">

<div style="margin-top: 0px; margin-bottom: 0px;" class="">I'm trying to apply both temperature and velocity flux boundary conditions at one of my boundaries. I am unsure, however, how to apply this in userbc in the usr file. I can set one of the two by having
an 'f' in the box file (for just one variable) and then defining 'flux =' in userbc. How do I do this for both temperature and velocity? Is there separate term for flux for temperature and flux for velocity?</div>
