EcosimPro as a pure equations solver

Apart from all the qualities which make EcosimPro a powerful simulation environment for very complex hybrid systems (thermal fluid dynamics, chemical, mechanical, electrical, ...), its mathematical capabilities to solve differential-algebraic equation systems can be used to solve any mathematical problem of this type; in other words, it can be used as a mathematical calculation tool.

EcosimPro uses a modelling language that is very easy to learn, so entering a system of equations to be solved is a trivial task. It also has a graphical user interface similar to Microsoft Visual Studio, so its use is quite intuitive.

Types of equations

EcosimPro can solve any type of linear, non-linear, differential-algebraic (DAE) or ordinary-differential (ODE) equation. Additionally, when modelling, it is possible to enter discrete events so that the simulation halts enabling the user to change the conditions.

The solvers used are DASSL (L. Petzold) for the DAEs, and fourth order Runge-Kutta for the ODEs. It also has a Newton-Raphson based solver for non-linear equations, and its own algorithms for extracting roots.

Professional applications

EcosimPro has been used by many companies and universities in a very wide number of fields (aeronautical, biological, chemical, control, energy generation, hydraulic systems, industrial process, optimisation, space,...).

Part of these works have been recompiled and categorised in some articles which are available for download, both in English and Spanish.
