Abstract : The oodlesDST code is based on OpenFOAM software and performs Large Eddy Simulations of turbulent fluid flows. The code contains a number of specialized subgrid scale turbulence models and wall models. This report describes these models in sufficient detail to allow a new user of the code to make informed decisions regarding the use of these models for particular applications. An overview of the code structure is given and typical solver settings and discretization choices have been illustrated by applying the code to the separation and reattachment of a turbulent boundary layer on a three-dimensional curved ramp. The simulated results are compared with experimental results as well as previous numerical simulations.
