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.

To fix this problem, we can install more using the command below.
