<p>Dear Neks,</p>
<p><br>
</p>
<p>I have modified the turbChannel example (available in v17.0) to a
WRLES flat plate test case and validated it against DNS data. <br>
</p>
<p>One step further, I am now imposing traction boundary condition
on the wall, i.e tauw (TRX,TRZ) and computing the wall shear
stress thanks to torque_calc routine. The computed wall shear
stress corresponds to the one I am imposing. However the fluid
accelerates at the wall and never converges to a value.</p>
<p><br>
</p>
<p>1. The wall shear stress in correct but the velocity increases
over time. How can this be possible ?</p>
<p>2. Are you aware of the formalism surrounding traction boundary
condition in the discrete equations ?</p>
<p><br>
</p>
<p>Sincerely,</p>
<p>Armand.<br>
