About OpenFLUID

OpenFLUID is a software environment for spatial modelling in landscapes. Based on an explicit representation of spatial objects and their interactions, OpenFLUID is designed for modelling dynamics at different spatial and temporal scales. It provides functionalities for the development and integration of computational codes, model coupling, parameterization and execution of simulations. It is also a collaborative framework for the capitalization and sharing of multi-disciplinary scientific models.
OpenFLUID has already been applied in various contexts: hydrology, diffuse pollution, agricultural practices, erosion, land use planning, etc. Free, open-source and based on open standards, OpenFLUID is fully commited to open and reproducible science approaches.

sudo dnf install /path/to/<openfluidpackagfile>.rpm


  1. Install Brew if not already present (see also
/usr/bin/ruby -e "$(curl -fsSL"
  1. Add OpenFLUID tap for Brew
brew tap OpenFLUID/openfluid
  1. Install OpenFLUID using Brew (with --no-quarantine option to avoid Gatekeeper restrictions in recent MacOS versions)
brew cask install --no-quarantine openfluid
