<div dir="ltr">Hey Paul,<div><br></div><div>In my case, the time step is very small, and I want the scalars (initially a small gaussian blob in the center of the cylindrical domain) to hit the wall. For that to happen I need too many files to print out. Right now I am printing them out at 0.1*(vertical diffusion time) and get say 100 files to hit the wall. While my time step is 1e-4 * (vertical diffusion time) for RB convection.</div><div><br></div><div>Thanks,</div><div>Saikat</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><span style="background-color:rgb(255,255,255)"><font color="#444444" face="georgia, serif" size="2">Saikat Mukherjee,</font></span></div><div dir="ltr"><font color="#444444" face="georgia, serif" size="2">PhD Student,</font></div><div dir="ltr"><font color="#444444" face="georgia, serif" size="2">Paul Research Group - <a href="http://www.me.vt.edu/mpaul/" target="_blank">http://www.me.vt.edu/mpaul/</a><br></font><div><span style="background-color:rgb(255,255,255)"><font color="#444444" face="georgia, serif" size="2">Engineering Science and Mechanics,</font></span></div><div><span style="background-color:rgb(255,255,255)"><font color="#444444" face="georgia, serif" size="2">Virginia Tech.</font></span></div></div></div></div></div></div></div></div></div></div>

Hi Saikat,
<div><br>
</div>
<div>Any reason to not save a few time steps and apply finite differences?</div>

<div dir="ltr">Hello Neks,
<div><br>
</div>
<div>I want to find out the time derivative of Scalar field in my Rayleigh Benard calculations. Can you give me any idea how to go about it? Right now I get the scalar field only along with the primitive variables. But I want to get the time derivative field
of the scalars (dc/dt).</div>
<div><br>

<div>Thanks,</div>
