Buildings.Utilities.Psychrometrics.Functions.BaseClasses.Examples.DewPointTemperatureDerivativeCheck

Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

Parameters

Type	Name	Default	Description
Real	uniCon	1	Constant to convert units [K/s]

Modelica definition

model DewPointTemperatureDerivativeCheck 
  "Model to test correct implementation of derivative"
  extends Modelica.Icons.Example;

    Real x;
    Real y;
    parameter Real uniCon(unit="K/s") = 1 "Constant to convert units";
initial equation 
     y=x;
equation 
    x=Buildings.Utilities.Psychrometrics.Functions.pW_TDewPoi(  T=time*uniCon);
    der(y)=der(x);
    assert(abs(x-y) < 1E-2, "Model has an error");
end DewPointTemperatureDerivativeCheck;

Buildings.Utilities.Psychrometrics.Functions.BaseClasses.Examples.DewPointTemperatureDerivativeCheck_amb

Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

Parameters

Type	Name	Default	Description
Real	uniCon	1	Constant to convert units [K/s]

Modelica definition

model DewPointTemperatureDerivativeCheck_amb 
  "Model to test correct implementation of derivative"
  extends Modelica.Icons.Example;

  Real x;
  Real y;
  parameter Real uniCon(unit="K/s") = 1 "Constant to convert units";
initial equation

end DewPointTemperatureDerivativeCheck_amb;

Buildings.Utilities.Psychrometrics.Functions.BaseClasses.Examples.InverseDewPointTemperatureDerivativeCheck_amb

Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

Parameters

Type	Name	Default	Description
Real	uniCon	1	Constant to convert units [Pa/s]

Modelica definition

model InverseDewPointTemperatureDerivativeCheck_amb 
  "Model to test correct implementation of derivative"
  extends Modelica.Icons.Example;

  Real x;
  Real y;
  parameter Real uniCon(unit="Pa/s") = 1 "Constant to convert units";
initial equation 
  y = x;
equation 
  x = Buildings.Utilities.Psychrometrics.Functions.TDewPoi_pW_amb(p_w=time*uniCon);
  der(y) = der(x);
  assert(abs(x - y) < 1E-2, "Model has an error");
end InverseDewPointTemperatureDerivativeCheck_amb;

Buildings.Utilities.Psychrometrics.Functions.BaseClasses.Examples.WaterVaporPressureDerivativeCheck

Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.
