hi,
while I am executing the "DCmotorcircuit model"in DR control tutorial in O M N book
an error is occurring
this is the code

loadModel(Modelica);

model DCMotorCircuit
  Modelica.Electrical.Analog.Basic.Resistor     resistor1(R = 10);
  Modelica.Electrical.Analog.Basic.Inductor     inductor1(L = 0.2);
  Modelica.Electrical.Analog.Basic.Ground       ground1;
  //Modelica.Mechanics.Rotational.Components.Inertia      inertia1(J = 1);   
  //Modelica 3.1
  Modelica.Mechanics.Rotational.Inertia         inertia1(J = 1);
  Modelica.Electrical.Analog.Basic.EMF          emf1;
  Modelica.Blocks.Sources.Step                  step1;
  Modelica.Electrical.Analog.Sources.SignalVoltage signalVoltage1;
equation
  //connect(step1.outport, signalVoltage1.inPort);
  connect(step1.y, signalVoltage1.v);
  connect(signalVoltage1.p, resistor1.p);
  connect(resistor1.n, inductor1.p);
  connect(inductor1.n, emf1.p);
  connect(emf1.flange_b, inertia1.flange_a);
  connect(signalVoltage1.n, ground1.p);
  connect(ground1.p, emf1.n);
end DCMotorCircuit;

simulate( DCMotorCircuit, stopTime=150 )

the following error occured

record SimulationResult
    resultFile = "",
    messages = "Simulation failed for model: DCMotorCircuit
[<interactive>:2:3-2:66:writable] Error: Class Modelica.Electrical.Analog.Basic.Resistor not found in scope DCMotorCircuit.
Error: Error occurred while flattening model DCMotorCircuit
"
end SimulationResult;

plot( signalVoltage1.i );

i am using modelica 3.2

any one help to resolve this problem

the libraries are found in my modelica library

hi,
i am beginner  to this modelica environment

please clarify whether debugging and step by step code execution is available or not

if possible please give the details

if any other options available please suggest

Thank you
