**Gerris Flow Solver**

**Gerris** is a Free Software program for the solution of the partial differential equations describing fluid flow. The source code is available free of charge under the Free Software GPL license.

Gerris is supported by NIWA (National Institute of Water and Atmospheric research).

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
