## GRIN

**Abstract**
- GRIN is a package to solve elliptic problems in two
dimensions using Green's functions. The advantage of
the Green's function formalism compared to a finite
element approach for instance, is that one is left
with a lower dimensional problem, namely the one of
computing line integral in two-dimensions. Because
the Green's functions can be chosen so as to vanish
at infinity, this formalism is particularly applicable
to problems where the domain is large or extends to
infinity. Another typical application of the Green's
function formalism is when one is only interested in
determining the field on selected contours.
