Hello all, Thanks for the replies, I think my log-file was too big even after compression and stuck in moderator approval for the list. But here is the part of the log-file where the problem starts. I have attached a google drive link which has the log file and .rea file, the Lewis Number is set in line 133 of the .rea file after parameter 128 (p128).

Hey all,
Thanks for the replies. Attached are the log file and the .rea file where I set my Lewis Number. The Lewis Number is set after parameter 128 (p128) at line 133 of the .rea file.

Salkat,
could you please be more specific when you write ‘ I have not been successful’? Do you get an error message?

Hello Neks,
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.
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?
Thanks, Saikat
