Flow-Organisms Simulation System FOrgSimS

A computer simulating software FOrgSimS (Flow-Organisms Simulation System) is designed to model interactions between organisms (e.g. algae, insects, fish) and turbulent environments within numerically simulated morphologies. Development of the FOrgSimS is primarily motivated by a necessity to better understand survival of fish at the meso-scale habitats of river reaches with engineering structures (e.g. groynes) and natural features (e.g. confluence) during a passage of toxic contaminants. Although the first version of FOrgSimS is focused on the fish-flow interactions modeling in rivers, it is planned that the system will be expanded to model more general environments including airscapes, floodplains with riparian vegetation, insects and animals related by host-seeking behavior. The FOrgSimS is developed using object-oriented architecture in C++. Present document provides detailed description of the modeling system including theoretical backgrounds, test data, validation and examples of modeling.
