<div dir="ltr">Hi all,<div><br></div><div>I want to implicitly solve a linear advection equation of the form:</div><div>dQ/dt + div(u*Q) = 0</div><div><br></div><div>for a scalar quantity Q, with some known velocity field u. Note that it is purely advection with no diffusion term. </div><div><br></div><div>Is there a recommended solver/preconditioner combination to solve something like this?</div><div><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><br><b>Nishant Nangia</b><div>Northwestern University<br><div>Ph.D. Candidate | Engineering Sciences and Applied Mathematics<br></div></div><div><span style="font-family:arial;font-size:small">Tech L386</span><br></div></div></div></div></div></div>
