5009	Issue with parameter bindings involving Complex equations in the NF	Francesco Casella	Per Östlund	"Please consider the following test model
{{{
model TestComplexParameter
  import CM = Modelica.ComplexMath;
  parameter Real v_abs_start = 2, v_phase_start = 0.5;
  parameter Modelica.SIunits.ComplexVoltage v_start = CM.fromPolar(v_abs_start, v_phase_start);
  Modelica.SIunits.ComplexVoltage v(re(start=v_start.re), im(start=v_start.im));
equation
  CM.'abs'(v) = 1;
  CM.arg(v) = 0.5;
end TestComplexParameter;
}}}
When building the model with the NF, the generated {{{TestComplex_06inz.c}}} C-code contains:
{{{
/*
 equation index: 1
 type: ALGORITHM
 
   v_start := Complex(v_abs_start * cos(v_phase_start), v_abs_start * sin(v_phase_start));
 */
void TestComplex_eqFunction_1(DATA *data, threadData_t *threadData)
{
  TRACE_PUSH
  const int equationIndexes[2] = {1,1};
  Complex tmp0;
  Modelica_SIunits_ComplexVoltage tmp1;
  tmp0._re = (data->simulationInfo->realParameter[0]) * (cos(data->simulationInfo->realParameter[1]));
  tmp0._im = (data->simulationInfo->realParameter[0]) * (sin(data->simulationInfo->realParameter[1]));
  tmp1 = tmp0;
  data->simulationInfo->realParameter[3] = tmp1._re;
  data->simulationInfo->realParameter[2] = tmp1._im;
  TRACE_POP
}
}}}
which breaks the compiler because {{{Modelica_SIunits_ComplexVoltage}}} is undefined.

I understand binding equations for Complex parameters are now moved to the initial equations. For some reason, the call to the {{{fromPolar}}} function is not inlined correctly, as it is instead the case for regular binding equations, such as in 
{{{
model TestComplexVariable
  import CM = Modelica.ComplexMath;
  Modelica.SIunits.ComplexVoltage v = CM.fromPolar(time, sin(time));
end TestComplexVariable;
}}}
Perhaps the {{{Inline}}} annotation of the {{{fromPolar}}} function is lost on these added initial equations?"	defect	closed	high	2.0.0	New Instantiation		fixed
