Screenshot of GfsView displaying the result of a Gerris calculation of flow past a sphere at Reynolds 300. The complex 3D structure of the periodic wake is illustrated by the isosurface of the Lambda2 criterion of Jeong and Hussain. The vertical cross-section is coloured according to the vorticity. The horizontal cross-section displays the depth of refinement of the adaptive mesh.

Animation (2.2 MB) of the evolution of an initially random distribution of vorticity in 2D. The incompressible Euler equations are solved. The classical 2D vortex merging process is clearly illustrated. A uniform Cartesian grid is used for the spatial discretisation.

Test of scalability of the parallel solver. The "initial random vorticity" problem (see animation above) is solved on 1,2,4,8,16,32 and 64 processors of a CRAY T3E. Each set of points is for a different problem size (indicated in the legend). The speedup obtained is very close to (and sometimes above) the optimum. Superlinear speedups are obtained due to the better use of the cache memory by processors working on smaller problems.

A few examples of what Gerris can do. See the examples and test suite for more.
