context_page_description: Gerris is computer software in the field of computational fluid dynamics. Gerris was released as free and open-source software, subject to the requirements of the GNU General Public License, version 2 or any later.
context_section_description: Gerris solves the Navier–Stokes equations in 2 or 3 dimensions, allowing to model industrial fluids (aerodynamics, internal flows, etc.) or for instance, the mechanics of droplets, thanks to an accurate formulation of multiphase flows (including surface tension). Actually, the latter field of study is the reason why the software shares the same name as the insect genus.
  Gerris also provides features relevant to geophysical flows:
  ocean tide
  tsunamis
  river flow
  eddies in the ocean
  sea state (surface waves)
  Flow types #1 to #3 were studied using the shallow-water solver included in Gerris, case #4 brings in the primitives equations and application #5 relies on the spectral equations for generation/propagation/dissipation of swell (and/or wind sea): for this purpose Gerris makes use of the source terms from WaveWatchIII.
  Lastly, one can note that the (non-hydrostatic) Navier–Stokes solver was also used in the ocean to study:
  fluvial plumes
  internal waves
  hydrothermal convection
  On the contrary Gerris does not allow (in its current status) the modeling of compressible fluids (supersonic flows).
