Numerical Algorithms

Various numerical methods are used in BANG. They may be based on finite elements or finite volume methods, or stochastic methods for individual agents. Algorithmic improvements are needed in order to take into account the specificity of each model, of their coupling, or their 3D features. Among them we can mention

• Well-balanced schemes for shallow water system.

• Free-surface Navier-Stokes solvers based on a multilayer St-Venant approach.

• Deterministic and stochastic agent based models for the simulation of multi-cellular systems.
