Gerris Description

Gerris - Free and open source application for the solution of the partial differential equations describing fluid flow Gerris is a free and open source application for the solution of the partial differential equations describing fluid flow.Gerris uses an "embedded boundary" technique. Grid generation reduces to the computation of the "shape" (surface and volume fractions) of Cartesian (cubic) cells cut by the solid boundaries. These "boolean operations" between solids are performed automatically using GTS (the GNU Triangulated Surface Library). The cells cut by the boundaries can then be refined automatically using the quad/octree structure of the discretisation.Mesh generation is entirely automatic and will work for any input geometry (provided the mesh is topologically consistent, i.e. an orientable non-self-intersecting manifold).Here are some key features of "Gerris":· 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 flowsRequirements:· Xcode· X11· Fink· darcsNOTE: For installation on your Mac follow the tutorial provided by the developer here: .
