IDAES is a process systems engineering framework designed for modelling, simulation, optimisation and analysis of complex chemical and energy processes. It provides an equation-oriented environment built around Pyomo and is intended for applications ranging from individual unit operations to complete process flowsheets.
The framework uses a modular approach. Process models can combine unit operations with thermophysical property packages and reaction packages, allowing components to be reused when constructing different processes. Models are expressed as systems of algebraic and differential equations which can then be passed to compatible numerical solvers.
IDAES includes models for equipment such as reactors, heaters, heat exchangers, compressors, pumps, separators and other common process units. It also provides tools for defining physical properties, reaction systems and process streams. Connections between individual units can be assembled into flowsheets representing larger chemical or energy systems.
The framework extends beyond straightforward steady-state simulation. It supports dynamic models, parameter estimation, optimisation, scaling tools, diagnostics and approaches for analysing complex process systems. Its Python API means models can also be combined with the wider scientific Python ecosystem.
IDAES is primarily aimed at engineers and researchers who need a programmable process modelling environment rather than a conventional point-and-click process simulator. Linux is explicitly supported, and the project provides command-line tools alongside its Python interface.
This is free and open source software.
