About SELFE

SELFE (Semi-implicit Eulerian-Lagrangian Finite Element) is an open-source community-supported modelling system, based on unstructured grids, designed for the effective simulation of 3D baroclinic circulation across river-to-ocean scales. It uses a semi-implicit finite-element Eulerian-Lagrangian algorithm to solve the Navier-Stokes equations (in either hydrostatic and non-hydrostatic form), written to realistically address a wide range of physical processes and of atmospheric, ocean and river forcings. The numerical algorithm is high-order, and stable and computationally efficient (but slightly more expensive than ELCIRC). Although not guarenteed in the numerical scheme, the volume conservation is generally good. It also naturally incorporates wetting and drying of tidal flats. While originally developed to meet specific modeling challenges for the Columbia River, SELFE has been extensively tested against standard ocean/coastal benchmarks and applied to a number of bays/estuaries around the world, in the context of general circulation, tsunami and storm surge inundation, internal waves, and recently, oil spill, sediment transport, coastal ecology, and wave-current interaction.
