Dynamic Plant Modelling
and Simulation

Build, simulate, calibrate and analyse mathematical plant models — all in one desktop application. From first equation to validated predictions.

All the modelling tools you need

Six integrated modules, one application.
AI agent friendly command line mode.

Data I/O

Import measurement data from CSV or text files with flexible format configuration. Export simulation, calibration, sensitivity, and uncertainty results for further analysis.

Model Editor

Write plant models using familiar mathematical notation with advanced editor features to make model development faster and more reliable.

Simulation

Simulate dynamic models using various solvers. Simulation results can be directly visualized using dashboard charts and/or compared to external data.

Calibration

Automatically fit your model parameters to experimental data and calculate confidence information. Supports both static calibration and moving-window calibration.

Sensitivity and Identifiability Analysis

Identify which model parameters have the greatest influence on your model variables and use this for model understanding, to guide model simplification, and for experimental design.

Uncertainty Analysis

Propagate parameter uncertainty through your model using Latin Hypercube sampling. Understand the range of plausible model outputs given the variability in your model parameters.
