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
