<div dir="ltr">Hello Neks,<div><br></div><div>I am solving a Reaction Advection Diffusion equation, where with my non-dimensionalization, the Lewis Number(Le) is the parameter multiplying the Laplacian. That is, Le is the non-dimensional Diffusion co-efficient of the species. Currently I can do Le = 0.1, but to reduce it further down to 0.01, or 0.001, the spatial resolution has to be increased. I tried doing that increasing the GLL points in SIZE file by increasing the lx1, lxd, but till now I have been unsuccessful.</div><div><br></div><div>I am aware there is a special filtering that can be used( Fischer and Mullen, 2001). My question is how to implement that in my .usr file. Is there a routine?</div><div><br></div><div>Thanks,</div><div>Saikat</div><div><br></div><div><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>
