 FLUMEN (FLUvial Modelling ENgine) solves the shallow water equations on unstructured adaptive meshes. It is an extension of the standard Hydro2de program and 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
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 online manual for more details on how to use Flumen.
