Subject: Program to add to resources
I have attached to this email a code written in C which solves non-linear
time-dependent 2-D eqns. In particular, the equation should have the form:
(d/dt)u= (\nabla^2) u + g(x,y,u) + f(x,y)
with periodic boundary conditions. The function g is easily tunable. The
code is written as a primarily instructional code for a student who might
have some familiarity with linear multigrid, and would want a slightly
more general approach, or a student who can solve a linear boundary
equation, but is now looking to include time. I haven't provided overly
detailed explanations of what restriction or prolongation do, but
I've been more detailed in how the linearization occurs, and what happens
as a function of time.
I would be most pleased if you could include this with your selection of
codes available for the public.
I am the primary author of the code, and may be contacted at the current
address: s.barsky@ucl.ac.uk or barsky@thaumas.net
Thank you,
Sandra Barsky
