Gerris is a system for the solution of the partial differential equations describing fluid flow. . A brief summary of its main (current) features: . * Solves the time-dependent incompressible variable-density Euler, Stokes or Navier-Stokes equations * Adaptive mesh refinement: the resolution is adapted dynamically to the features of the flow * Entirely automatic mesh generation in complex geometries * Second-order in space and time * Unlimited number of advected/diffused passive tracers * Flexible specification of additional source terms * Portable parallel support using the MPI library * Volume of Fluid advection scheme for interfacial flows . This package has MPI support built in.
