5321	The NF does not handle overconstrained connections correctly	Francesco Casella	Per Östlund	"Please check [https://libraries.openmodelica.org/branches/newInst/Buildings_latest/Buildings_latest.html Buildings.Electrical.AC.ThreePhasesUnbalanced.Lines.Examples.ACLineMatrix_RL]. The NF fails with
{{{
[1] 19:06:18 Symbolic Error
Too many equations, over-determined system.
The model has 916 equation(s) and 913 variable(s).
}}}
while the OF leads to [https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Electrical.AC.ThreePhasesUnbalanced.Lines.Examples.ACLineMatrix_RL.sim successful simulation].

I guess overconstrained connections are not handled properly, so there are eventually more equations than unknowns in the flat model."	defect	closed	high	2.0.0	New Instantiation		fixed		Michael Wetter
