parameter unable to change through _ini.xml

Nov-10-20 12:15:53

Hi,

my intention is to change a parameter of a component through the _init.xml:

The model is declared as:

Code:


model ModelA

  ...

  parameter Types.ActivePower PRefConst = 0

  ...

  Types.ActivePower PRef(nominal = SNom) =  PRefConst

   ...

end ModelA;

During the instantiation of ModelA, the PRefConst is assigned to a value:

Code:


  model_a ModelA(..., PRefConst = 14.9e6, ...);

In the compiled C code, it can be noticed that the PRefConst's value is assigned hard-coded:

Code:




/*

equation index: 6068

type: SIMPLE_ASSIGN

model_a .PRefConst = 14900000.0

*/

void modelName_eqFunction_6068(DATA *data, threadData_t *threadData)

{

  TRACE_PUSH

  const int equationIndexes[2] = {1,6068};

  data->simulationInfo->realParameter[1565] /* model_a .PRefConst PARAM */ = 14900000.0;

  TRACE_POP

}



/*

equation index: 6067

type: SIMPLE_ASSIGN

model_a .PRef = model_a .PRefConst

*/

void modelName_eqFunction_6067(DATA *data, threadData_t *threadData)

{

  TRACE_PUSH

  const int equationIndexes[2] = {1,6067};

  data->simulationInfo->realParameter[1564] /* model_a .PRef PARAM */ = data->simulationInfo->realParameter[1565] /* model_a .PRefConst PARAM */;

  TRACE_POP

}

So that in the end even I chang the value of PRefConst in the _init.xml file, the value of PRef is still 14900000.0, because it is already assigned by the original PRefConst's value in the C code. How can I avoid this? Maybe through some options in preOptModules or postOptModules? 
My current preOptModules is set to

Code:


setPreOptModules("normalInlineFunction,expandDerOperator,clockPartitioning,findStateOrder,inlineArrayEqn,encapsulateWhenConditions")
