Dear Paul,<div><br></div><div>I want to compute grad(Temp_field) for Rayleigh-Benard convection simulation. I found two functions in navier1.f, "opgrad" and "opgradt" which compute grad(scalar_field).</div>
<div><br></div><div>Which one of these functions should I use? Please help.</div><div><br></div><div>with regards,</div><div>Supriyo<br clear="all"><br>-- <br>Dr. Supriyo Paul                                       <br>Senior Project Scientist                   <br>
