Re: SOR technique for semiconductor continuity equation

Ah, thank you for that. I know conditions 1 and 3 are met and I
suspect condition 2 is also met, so I will try that out.

Does optimal omega theory mean that I can use w_opt = 2 / ( 1 +
sin(pi/(n+1)) ) with n the iteration step if I use a 2 dimensional
square lattice?

And finally (sorry for asking so many questions), Will this value of
omega work for the 4th and 5th lines of the above matrix, where the
equations are respectively:

c7.n3 - (c8.n4 +k.n4.n5) = 0
c10.n6 - (c9.n5 + k.n4.n5) = 0

It just seems odd that the optimum omega for these two equations should
be the same as the optium omega for all the other equations (which are
essentially the same).

Many thanks for all your help,

Chris
