Real-Space Cellular Automaton Laboratory

ReSCAL is a generator of 3D multiphysics, markovian and stochastic cellular automata with continuous time (more info).

This project aims to provide spatio-temporal modeling of geological interfaces. It is conducted with the Geomorphology team and the Laboratoire de Dynamique des Fluides Géologiques, within the Institut de Physique du Globe de Paris.

Key features:
  • transitions of neighboring cells
  • choice of the geometry and boundary conditions
  • computation of simulated time
  • detection of solid surfaces and computation of the slope
  • avalanche mechanisms
  • correlations between transitions
  • localized control and forcing of the transition rates
  • coupling with a multispeed lattice gas automaton
  • polymorphism of the cells

Graphical interface:
  • real-time rendering
  • light shading
  • horizontal and vertical planes
  • visualization of the hydrodynamical flow

Parallelized code with OpenMP and MPI libraries (MPI code not included in the GPL version).

Examples of application domains:
