@phannebohm any update on this?

@perost please take care of this at your earliest convenience. @kabdelhak agrees on the approach, and will remove the default setting of -d=arrayConnect when --newBackend is activated, once this fix...

@kabdelhak I just started a newInst-newBackend library test job. Let's see what happens with this change.

I'm still unsure about this heuristics. I'd say 100 is too large anyway, why would we want to generate 99 separate code chunks to handle 99 connect statements when we...

Anyway, I'm still a totally confused about what is going on with the flags. First of all, in the [ScalableTestSuite report using the NF and the old backend](https://libraries.openmodelica.org/branches/master/ScalableTestSuite_noopt/ScalableTestSuite_noopt.html), all models...

A second thing I don't understand in that [test report](https://libraries.openmodelica.org/branches/newInst-newBackend/ScalableTestSuite_noopt/ScalableTestSuite_noopt.html) is how the TransmissionLineModelica models fail. If you check [TransmissionLineModelica_N_10](https://libraries.openmodelica.org/branches/newInst-newBackend/ScalableTestSuite_noopt/files/ScalableTestSuite_noopt_ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineModelica_N_10.err), it fails with ``` Internal error NBackendDAE.lowerEquation failed for connect(transmissionline.R[i].n,...
