OpenModelica from OSMC. • Dymola from JModelica.org from Modelon where the input-output causality is fixed. Example: a resistor equation: R*i = v;.

JModelica.org is a commercial software platform based on the Modelica modeling language for modeling, simulating, optimizing and analyzing complex dynamic systems. The platform is maintained and developed by Modelon AB in collaboration with academic and industrial institutions, notably Lund University and the Lund Center for Control of Complex Systems (LCCC).

Modelica, executable UML o Jmodelica.org (Modelon) Modelica Modeling and Simulation (M&S) Since OpenModelica translates the Modelica source code into DAEs, this I have been using OpenModelica for many months successfully. However Dymola seems to promise: - a faster simulation time (actually some of my models last for some days in being simulated) - full co-simulation (now OpenModelica FMU does not use DASSL so it does not serve for the models I run) What is your opinion? Kind regards Koldo JModelica.org offers support for the Functional Mock-up Interface (FMI) standard. FMI specifies a format for exchange of compiled dynamic models and it is supported by a large number of modeling and simulation tools, including established Modelica tools such as Dymola, OpenModelica, and SimulationX. FMI defines a model OpenModelica includes SystemDynamics library with World modeling.

Personally I would prefer OpenModelica as it is cross-platform, easy to use/install, comes with many other supporting tools, has very good documentation for learning, and has a reasonably good community around it, which is very essential. Thanks for A2A. I don’t know much about Simscape except that its a part of Simulink, so assuming you know about Simscape, I will just tel you about OpenModelica * Its non-proprietary, meaning you don't have to spend a lot of money to buy the softw My opinion is that Mathworks saw Modelica arriving, decided not to buy into it and rushed a product out to try to kill it off. Other companies took Modelica (which is a language, not a product) and implemented it. The open Modelica compilers are getting better.

Important run environments for Modelica are OpenModelica, JModelica and Dymola. While OpenModelica and JModelica are free and open source platforms, Dymola is a commercial platform. Personally I would prefer OpenModelica as it is cross-platform, easy to use/install, comes with many other supporting tools, has very good documentation for learning, and has a reasonably good community around it, which is very essential.

The new frontend was validated against large models from the ScalableTestSuite library and Modelica Standard Library, with good results. I worked with OpenModelica and JModelica in my bachelor degree.

OpenModelica claim to support 98% of the language now.

I think they chose OpenModelica because it has a friendly environmen to model with the blocks paradigm (close as SimuLink but with differences) and so many libraries while JModelica is more focused on dynamic optimization and requires programming skills in Python language (I think that it’s more difficult JModelica.org than OpenModelica).
