KratosShallowWaterApplication 9.4

KRATOS Multiphysics ("Kratos") is a framework for building parallel, multi-disciplinary simulation software, aiming at modularity, extensibility, and high performance. Kratos is written in C++, and counts with an extensive Python interface.

Shallow water application

This is a research application that provides a set of tools for oceanographic and hydrographic simulations over shallow domains. The background of the stabilization method is explained in [^1].

Dependencies

This application does not have other application dependencies at compile time. The following Python libraries may be required:

• scipy is used by the wave generator and by the benchmarks
• numpy is used to generate solitary waves and analytical solutions by the benchmarks

If the coupling with the Navier-Stokes equations is required [^2], add the following applications to compilation:

• HDF5Application
• MappingApplication
• PfemFluidDynamicsApplication
