OPTIMICA compiled steady state Modelica models exposes • Iteration variables and residuals • Cost function • Optimization variables (free variables) Interface to numerical optimization routine IPOPT available Optimization use cases • Component design/sizing • Set-point optimization • Parameter estimation STEADY-STATE OPTIMIZATION Python is compatible with Optimica and it is po s-sible to interact with Modelica and Optimica models through Python scripting (the Python interface of the Jmodelica.org platform is great for this). For exa m-ple, it enables the possibility to do parameter mani p-ulation s and to perform simulation and optimiz ation for a variety of setups. Modelica language called Optimica (Åkesson,2008) is used for this purpose. The model dynamics of the opti-mization models are described using Modelica. To add the extra information necessary to describe the optimiza-tion formulation Optimica is used. This means that con-straints, objective function and optimization time horizon In the upcoming 2016 product release, planned for May, IGNITE users will have instant access to Modelon’s advanced OPTIMICA Compiler Toolkit, a Modelica and Functional Mock-up Interface (FMI) based computational platform for system design. Integrating Ignite and Optimica offers a three-fold increase in the speed of compilation and simulation, providing significant time-savings.

Optimica

With regards to system requirements, OPTIMICA Compiler Toolkit is available as SaaS, Android, iPhone, and iPad software. Optimica consists of a few but powerful new language constructs that enable the user to express optimization problems using high-level descriptions on par with Modelica. Using the Optimica extension, optimization interval, cost function, constraints and information related to the numerical algorithm used to solve the problem can be specified. OPTIMICA compiled steady state Modelica models exposes • Iteration variables and residuals • Cost function • Optimization variables (free variables) Interface to numerical optimization routine IPOPT available Optimization use cases • Component design/sizing • Set-point optimization • Parameter estimation STEADY-STATE OPTIMIZATION Python is compatible with Optimica and it is po s-sible to interact with Modelica and Optimica models through Python scripting (the Python interface of the Jmodelica.org platform is great for this). For exa m-ple, it enables the possibility to do parameter mani p-ulation s and to perform simulation and optimiz ation for a variety of setups.

Modelon’s OPTIMICA Compiler Toolkit, the most advanced Modelica-based mathematical engine on the market, offers users a powerful solution for the automation, simulation and optimization of system behaviors throughout the model-based design cycle.

Siemens PLM Software partners with Modelon, plans to integrate Modelon's OPTIMICA Compiler Toolkit as the Modelica engine for Simcenter Amesim 17.

The Optimica extension is supported by a prototype compiler, the Optimica compiler, which has been used successfully in case studies. AB - In this paper, an extension of Modelica, entitled Optimica, is presented. Optimica extends Modelica with language constructs that enable formulation of dynamic optimization problems based on Modelica models. Optimica extension is supported by a prototype com-piler, the Optimicacompiler, which hasbeen used suc-cessfully in case studies.

In order to specify an optimization problem in Optimica, the new specialized class optimization is used. Inside such a class, Optimica constructs, as well as Model-ica constructs Optimica — An Extension of Modelica Supporting Dynamic Optimization.
