Contribution

It introduces a mixed approach combining rule-based and law-based descriptions at various scales within a fluid flow simulation.

Findings

Demonstrates the integration of multiple description levels in fluid simulation

Highlights the relevance of layered modeling for ecological applications

Proposes a categorization of models based on rules and laws

Abstract

We describe here our perception of complex systems, of how we feel the different layers of description are important part of a correct complex system simulation. We describe a rough models categorization between rules based and law based, of how these categories handled the levels of descriptions or scales. We then describe our fluid flow simulation, which combines different fineness of grain in a mixed approach of these categories. This simulation is built keeping in mind an ulterior use inside a more general aquatic ecosystem.
