4852	Structural parameter not substituted in regular equations by the NF	Francesco Casella	Per Östlund	"Please check the [https://libraries.openmodelica.org/branches/newInst/ScalableTestSuite/files/ScalableTestSuite_ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineModelica_N_10.err ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineModelica_N_10].

The following equation appears in the flattened model
{{{
  vol[N] = cur[N] * RL;
}}}

while the old front end correctly reports
{{{
  vol[10] = cur[10] * RL;
}}}

This in turn causes problems with the back-end, generating a bogus nonlinear equation that ultimately leads to simulation failure.
