PALM - Parallelized Large-eddy Simulation Model

Contact person

Björn Maronga

Description

High-performance Large-Eddy Simulation model for simulating atmospheric boundary layer flows with fully interactive embedded models (urban surface, land surface, radiation, cloud physics, pollutant dispersion). It has been developed as a turbulence-resolving large-eddy simulation (LES) model that is especially designed for performing on massively parallel computer architectures. By default, PALM has at least six prognostic quantities: the velocity components u, v, w on a Cartesian grid, the potential temperature θ, water vapor mixing ratio qv and possibly a passive scalar s. Furthermore, an additional equation is solved for either the subgrid-scale turbulent kinetic energy (SGS-TKE) e (LES mode, default) or the total turbulent kinetic energy. PALM is now an independent name based on a FORTRAN code.
