| Zusammenfassung |
| The Real Space Cellular Automaton Laboratory (ReSCAL) is a generator of 3D
multiphysics, markovian and stochastic cellular automata with continuous time.
The objective of this new software released under a GNU licence is to develop
interdisciplinary research collaboration to investigate the dynamics of complex geophysical
systems.
In a vast majority of cases, a numerical model is a set of physical variables (temperature,
pressure, velocity, etc...) that are recalculated over time according to some predetermined
rules or equations. Then, any point in space is entirely characterized by a local set of
parameters. This is not the case in ReSCAL where the only local variable is a state-parameter
that represent the different phases involved in the problem. An elementary cell represent a
given volume of real-space. Pairs of nearest neighbour cells are called doublet. For each
individual physical process that we take into account, there is a set of doublet transitions.
Using this approach we can model a wide range of physical-chemical or anthropological
processes.
Here, we present different ingredients of ReSCAL using published applications in
geosciences (Narteau et al. 2001 and 2009). We also show how ReSCAL can be developped
and used across many displines in geophysics and physical geography.
