The website and the associated github repository is hosting some documentation related to Lecode and the SgFm framework and not the source codes!
The code is not available as an open source package. However, there are possible agreements for non-commercial licensing so feel free to drop us a line to discuss possible collaborations and specific arrangements.
The Stratigraphic & Geomorphic Forward Modelling Framework (SgFm) is an innovative parallel numerical framework which aims to conduct coupled thermal-mechanical / stratigraphic-oceanic modelling of continental margins, sedimentary basins and associated landscape dynamics.
Lecode represents the first milestone in the development of the SgFm Framework and is designed to be the core scientific and numerical component of the infrastructure.
Lecode is a new numerical approach for simulating geomorphic and stratigraphic processes that combines open-channel flow with non-uniform sediment transport law, and semi-empirical diffusive mass wasting.
The main enhancements in Lecode implementation in comparison to other stratigraphic forward models are:
a fully parallelised approach, which increases the computational power and could take fully advantage of High Performance Computing (HPC) infrastructures,
a new formulation for open-channel transport and mass-wasting representation, ensuring conservation of mass and momentum
and allowing simultaneous erosion, transport and deposition,
a hybrid approach inspired by the simplified Marker-and-Cell theory and the Path-Sampling method to simulate flow
dynamics on a triangulated irregular network (TIN),
an innovative remeshing strategy of the TIN based on depressionless and flow accumulation algorithms,
which allows for variable spatial resolution and ensure the stability of open-channel flow hydrodynamics solution,
the representation of a virtually unlimited number of user-defined sediment classes.
