The new GBODE solver can handle systems with localized and/or multi-time-scale phenomena efficiently. However, it still has two major shortcomings. The first is that the current backend can only compute...

Increased max number of equations per C file to 1000

### Related Issues #12098 ### Purpose Partially reverts #11971, bringing back the number of equations per split file to 1000.

In ticket #11803, we are encountering weird behaviour related to String parameters that are specified as literal String constants with literal newline characters. Apparently, something goes wrong when initializing those...

See #11514 for a description of the problem. Adding @ClemensLinnhof to the loop.

Division by zero at initialization in Buildings.Experimental.DHC.Plants.Combined.Examples.AllElectricCWStorage

[Buildings.Experimental.DHC.Plants.Combined.Examples.AllElectricCWStorage](https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Experimental.DHC.Plants.Combined.Examples.AllElectricCWStorage.sim) fails with ``` LOG_ASSERT | debug | Buildings_latest_Buildings.Experimental.DHC.Plants.Combined.Examples.AllElectricCWStorage_functions.c:26107: Invalid root: (0)^(-1.5) ``` This needs to be investigated further. Follow-up of #11236.

Issues with the NB in ScalableTestSuite

The ScalableTestSuite library contains a number of simple models with large arrays that should now be able to run with the NB. I left out potentially problematic stuff like records,...

Improve the success rate of FMU export for the Buildings library

The success rate of exported FMU simulations is significantly lower than the success rate of native C runtime simulations. Some reports are linked here for the latest development version of...

The models [Buildings.Templates.ZoneEquipment.Validation.VAVBoxCoolingOnly](https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Templates.ZoneEquipment.Validation.VAVBoxCoolingOnly.err) and [Buildings.Templates.ZoneEquipment.Validation.VAVBoxReheat](https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Templates.ZoneEquipment.Validation.VAVBoxReheat.err) fail during `NFFlatten.resolveConnections` without any error.

Adding a top-level output to a model with incomplete initial equations makes CS-FMU produce completely wrong results
