ISIS Free
Halcrow have developed ISIS Free so that it offers an integrated 1D and 2D modelling software package. ISIS Free has all the same features as ISIS Professional, ISIS 2D and ISIS FAST which enable you to confidently apply it to smaller river modelling projects and to tackle different types of hydraulic conditions (i.e. flood risk assessments, flood mapping and design projects), and then seamlessly move to ISIS Professional, ISIS 2D or ISIS FAST should your project grow beyond the following restrictions: 250 1D nodes, 2,500 2D cells or DEM grid size of 2,500 cells.
ISIS Free can be downloaded at no cost and used on both commercial and non-commercial projects.
Users can sign up to an annual support and maintenance contract to gain direct access to the ISIS technical support team.
Should your project grow to need integrated 1D–2D modelling using ISIS and TUFLOW, sediment transport or water quality modelling then users can upgrade to ISIS Professional with the appropriate add-on modules
Key benefits of ISIS Free
- it’s FREE
- install it on as many computers as you like as its use is not limited
- undertake both steady and unsteady calculations
- use ISIS Mapper to build hydraulic models, analysis results, and visualise model outputs
- use the full range of structure (including logical rules)
- full use of hydrology units (including FEH, ReFH, USSCS)
- model floodplain flows through either 1D or 2D flow simulations
- seamlessly upgrade to ISIS Professional or ISIS 2D as a project grows

Download the ISIS Quick Start Guide
The ISIS team have produced a Quick Start Guide for ISIS Professional and ISIS 2D which takes users through the basics of creating a model in ISIS. These guides can also be applied to ISIS Free.
