FLUMEN (FLUvial Modelling ENgine)

solves the shallow water equations on unstructured adaptive meshes. It is especially useful for the modelling of hydraulic complex situations.

Main Features

based on the shallow water equations in conservation form
numerically stable in the presence of steep slopes (sub- and supercritical flow, hydraulic jumps)
models wetting and drying process (allowing dry starts and moveable boundaries)
mobile bed modul to account for deposition/erosion of sediments and bank failure
animated graphical output for intuitive analysis of complex flows
debris flow module
since version 3:

unlimited mesh sizes (depending on system RAM)
multi-threading (parallel processing)

since version 4:

transport/mixing of diluted quantities (temperature, salinity)
self-detecting of steady flow conditions
grafic-output at cross-sections

The program solves the depth-averaged shallow water equations on an unstructured mesh. The equations describe the flow field over moderate slopes where the pressure distribution is approximately hydrostatic.

A conservation form is used that remains valid in the presence of shocks (e.g. hydraulic jumps). The numerical method is based on an explicit cell-centred finite volume scheme.

See the manual for more details on how to use Flumen.
