At the moment I'm writing my masterthesis.I have to simulate an electrical curcuit with Open Modelica Notebook.
Now I'll discribe my problem:
I created several different classes (in the example Katholyt and Stromkreisaussen) and try to connect them.To fix them together I used the connect (resistor1.p,resistor2.n)  command as shown in the example (model Zweizeller). There was no error masage by compiling the model. But as I compared the values of the current at the connections, I figured out that the value of the current was not transfered from one class to the other class. How can I solve this problem?   

Here is the example:

class Katolyt
 
  Modelica.Electrical.Analog.Interfaces.Pin pinK;
  Modelica.Electrical.Analog.Interfaces.Pin pinKein;
  Modelica.Electrical.Analog.Basic.Resistor RCMo(R = 1.23);
  Modelica.Electrical.Analog.Basic.Resistor RCMu(R = 1.23);
  Modelica.Electrical.Analog.Interfaces.Pin pinKuaus;
  Modelica.Electrical.Analog.Interfaces.Pin pinKoaus;
  Modelica.Electrical.Analog.Interfaces.Pin pinKSein;
  Modelica.Electrical.Analog.Basic.Resistor RCo(R = 365.89);
  Modelica.Electrical.Analog.Basic.Resistor RCu(R = 365.89);
equation
  connect(pinK,pinKSein);
  connect(RCMu.p,pinKuaus);
  connect(RCMo.p,pinKoaus);
  connect(RCu.n,RCMu.n);
  connect(pinK,RCu.p);
  connect(pinK,pinKein);
  connect(RCo.n,pinK);
  connect(RCMo.n,RCo.p);
end Katolyt;

class Stromkreisaussen
 
  Modelica.Electrical.Analog.Interfaces.Pin pinStromein;
  Modelica.Electrical.Analog.Sources.ConstantCurrent Stromquelle(I = 1);
  Modelica.Electrical.Analog.Basic.Ground ground1;
  Modelica.Electrical.Analog.Interfaces.Pin pinStromaus;
equation
  connect(ground1.p,pinStromaus);
  connect(Stromquelle.p,pinStromein);
  connect(Stromquelle.n,ground1.p);
end Stromkreisaussen;

model Zweizeller
 
  Stromkreisaussen SKaussen;
  Anolyt HZ_01_minus;
  Zellspannung HZ1;
  Bipolarplatte BPP1;
  Katolyt HZ_01_plus;
 
equation
 
  connect(SKaussen.pinStromein,HZ_01_minus.pinAein);  // Seite Anolyt
  connect(HZ_01_minus.pinASein,HZ1.pinSein);
  connect(HZ_01_minus.pinAoaus,BPP1.pinRAMoaus);
  connect(HZ_01_minus.pinAuaus,BPP1.pinRAMuein);
  connect(HZ1.pinSaus,BPP1.pinBPPSein);
 
  connect(SKaussen.pinStromaus,HZ_01_plus.pinKein);  // Seite Katolyt
  connect(HZ_01_plus.pinKoaus,BPP1.pinRCMoaus);
  connect(HZ_01_plus.pinKuaus,BPP1.pinRCMuein);
  connect(HZ_01_plus.pinKSein,HZ1.pinSaus);
  connect(BPP1.pinBBPSaus,HZ1.pinSein);
 
end Zweizeller;
