<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>
