The NF does not handle conditional initial equations in sub-components of arrays of components correctly

[Francesco Casella]

Please check ​IBPSA.Fluid.MixingVolumes.BaseClasses.Validation.MixingVolumeHeatMoisturePort. The C-code compilation fails.

The root cause can be traced to the flat model containing equations such as

  if {true, false, false} then
    vol[1].dynBal.medium.p = vol[1].dynBal.p_start;
  end if;

which come from flattening an array of components vol[N], each of which contains a component dynBal with the following initial equations:

  if massDynamics == Modelica.Fluid.Types.Dynamics.FixedInitial then
    if initialize_p then
      medium.p = p_start;
    end if;
  else
    if massDynamics == Modelica.Fluid.Types.Dynamics.SteadyStateInitial then
      if initialize_p then
        der(medium.p) = 0;
      end if;
    end if;
  end if;
