Hello pco38

You can do it using sockets. There is a sample here (http://www.modelica-forum.com/forums/lo … p/t17.html) that is also referenced here (http://kempproject.blogspot.com.es/2013 … art-1.html).

This sample shows communication between an OpenModelica simulation and other programs for co-simulation.

It is very simple. If you find any problem please post it.

Now OpenModelica supports CORBA for communication with simulations. However most of times OpenModelica users do not need the sophisticated CORBA interface. A very simple message exchange library as the one shown in example is just enough. It would be great if OpenModelica project would include something similar.

Hello Koldo,

Thank you very much for your help. I'll try this method.

Best regards.

You're welcome

Anyway a question still unsolved for the Modelica model is to know exactly the simulation steps.

Now the model do not know when a step has finished. That is a matter of the solver and remains hidden for the model. This makes more difficult to couple simulations.
