Hi,
I have an equation which is as follows

When I solve this equation using the pdepe it shows an oscillation pattern at the edge as it is here (shown by arrow).

I changed my parameters a lot but this oscillation sometime reduces, but not zero. My bc are as follows
pl = 0;
ql = 1;

pr = 0;
qr = 1;
Can you tell how to reduce this oscillations?
Also, in the above equation, for the diffusion coefficient (sigma) the minimum value for which the pdepe converges is 1 below which the solution becomes diverging, it should not be actually.
