I added a PR to fix how subscripts are added to expressions (#13234). This allows this model to go further, but it fails during causalization now. Is `-d=mergeComponents` necessary? What...

I fixed the current issue with a kind of temporary fix in #13296 . The issue was record equations inside for loops. Initially i did not inline simple equalities because...

> OK. Are there plans to port tearing algorithms to the NB? There are plans and some theory about a new (more robust) tearing algorithm, but those are on the...

I do have a workaround for this specific case, but it could lead to errors in other places. If there is nothing speaking against it i would rather have the...

Thanks for the quick fix! it seems like the backend still does not parse it correctly but i will fix that :)

I fixed two problems, but there seem to be remaining problems. 1. Inlining did not work because incorrect record sizes were used. fixed with #13227 2. Record array lowering was...

After everything is merged the error message is: ``` Error: Internal error NBResolveSingularities.noIndexReduction failed. (10|16) Unmatched Variables ***************************** [ALGB] (10) flow Real[10] stack.module.pen.cathodeHeatPort.Q_flow (nominal = {1e6 for $f1 in 1:10})...

Unfortunately both models still fail, will have a look at [EHPTexamples.EV.FirstEV](https://libraries.openmodelica.org/branches/newInst-newBackend/EHPTexamples/files/EHPTexamples_EHPTexamples.EV.FirstEV.err) first.

Regarding [EHPTexamples.EV.FirstEV](https://libraries.openmodelica.org/branches/newInst-newBackend/EHPTexamples/files/EHPTexamples_EHPTexamples.EV.FirstEV.err): It seems like an index 2 system to me. There is the equation ``` [SCAL] (1) dragF.s = mass.s + 0.5 * mass.L ($RES_SIM_46) ``` with ``` (1)...
