<div class="gmail_quote"><br>Hi Nek's,<div><br></div><div><div><br></div><div>I'd like to use the adjoint linear solver. I have a problem concerning the outflow condition. The proper boundary condition would be:</div>
</div><div><br></div><div>(p-(1/Re)grad(u))*n=(U*n)*u</div>
<div><br></div><div>where: -n is the normal </div><div> - u is the adjoint velocity vector</div><div> - U is the base flow velocity vector</div><div> - p is the adjoint pressure</div><div>
-Re Reynolds number</div><div><br></div><div>How can I apply this condition on the outflow?</div><div><br></div><div>Best Regards,</div><div><br></div><div>Andrea</div><div><br></div><div><br></div><div><br></div>
