The OpenFOAM (Open Field Operation and
Manipulation) CFD toolbox can simulate anything
from complex fluid flows involving chemical
reactions, turbulence, and heat transfer, to solid
dynamics, electromagnetics, and the pricing of
financial options. It uses finite volume numerics
to solve systems of partial differential equations
ascribed on any 3D unstructured mesh of polyhedral
cells. The fluid flow solvers are developed within
a robust, implicit, pressure-velocity, iterative
solution framework, although alternative
techniques are applied to other continuum
mechanics solvers.
