Initial condition and Boundary Condition

[RAKSHIT]

Dear Friends,

                      I am working on pattern formation in reaction diffusion system(for example FitzHughNagumo Equation). I am using Finite difference approximation to simulate it. I want to know what kind of initial condition (random uniform or random normal) is realistic ? Also I would like to know what kind of boundary condition is more realistic for a reaction diffusion system like FitzHughNagumo.

I think you should try both. You can look at the results and decide
what you think looks more realistic.

For my Gray-Scott simulations I used about 10 different types of
random starting patterns, including some types of fairly plain random
noise, and some types that included rectangles of random values and
sizes scattered around the grid. No single type of starting pattern is
able to produce all the variety of patterns that are possible in
Gray-Scott.
