The purpose of XMDS2 is to simplify the process of creating
simulations that solve systems of initial-value first-order partial
and ordinary differential equations. Instead of going through the
error-prone process of writing by hand thousands of lines of code,
XMDS2 enables many problems to be described in a simple XML format.
From this XML description XMDS2 writes a C++ simulation that solves
the problem using fast algorithms. Anecdotally, the code generated
by XMDS2 is as fast as, or faster than, code hand-written by an
expert, but by using XMDS2 the time taken to produce the simulation
is significantly reduced.
