(synopsis "Framework for numerical simulation of fluid flow")
(description "OpenFOAM provides a set of solvers and methods for tackling
problems in the field of Computational Fluid Dynamics (CFD). It is written in
C++. Governing equations such as the Navier-Stokes equations can be solved in
integral form. Physical processes such as phase change, droplet transport and
chemical reaction can be modelled. Numerical methods are included to deal with
sharp gradients, such as those encountered in flows with shock waves and flows
with gas/liquid interfaces. Large problems may be split into smaller, connected
problems for efficient solution on parallel systems")
