Can Anyone help me in writing the codes for
A 2D square domain with Lx=Ly=200 and periodic boundary conditions.
The initial value of c for the square domain is specified by
c(x,y)=c0+ϵ[cos(0.105x)cos(0.11y)+[cos(0.13x)cos(0.087y)]2+cos(0.025x−0.15y)cos(0.07x−0.02y)],
where c0=0.5 and ϵ=0.01.
and same for the no flux condition
Thank you In Advance
