Welcome to DAE Tools Project!

DAE Tools is equation-based object-oriented modelling, simulation and optimisation software. Its Hybrid approach to mathematical modelling lets you easily develop models of complex multiscale/multiphysics processes/phenomena with complex schedules and perform various activities on them such as simulation, sensitivity analysis, optimisation, parameter estimation, code-generation and model exchange.
