OpenModelica and FMU example

Apr-06-14 17:32:13

Hi!
I am trying a simple example with Modelica and FMUs but I cannot get it to work. Here is the example I am trying to run:
I have the following two models:

TestFMU1.mo

Code:


model TestFMU1

  parameter Real p = 1.0;

  connector TestOutputConnector

    output Real value;

  end TestOutputConnector;

  TestOutputConnector c;

equation 

  c.value = p;

end TestFMU1;

TestFMU2.mo

Code:


model TestFMU2

  Real result;

  connector TestInputConnector

    input Real value;

  end TestInputConnector;

  TestInputConnector c;

equation 

  result = c.value;

end TestFMU2;

In OpenModelica shell I export these models to FMU with

Code:


>> loadFile("TestFMU1.mo")

>> translateModelFMU(TestFMU1)

... and this went fine. But when trying the same for TestFMU2

.. I get the following error(s):

Code:


>> translateModelFMU(TestFMU2)

What I am doing wrong?

I have some suggestions.

Don't you think that the connector must be defined outside your model :

Code:


connector TestOutputConnector

  output Real value;

end TestOutputConnector;

model TestFMU1

  parameter Real p = 1.0;

  TestOutputConnector c;

equation 

  c.value = p;

end TestFMU1;

The name of your model is TestFMU2 and you want to build oa model called TestFMU1.
