4711	DrumBoiler model unnecessarily slow due to lack of analytic jacobiann	Francesco Casella	Patrick Täuber	"The model {{{Modelica.Fluid.Examples.DrumBoiler.DrumBoiler}}} is slower than necessary because of an implicit system that is not recognized as linear and thus solved iteratively, which wastes a lot of time because of the computation involved and the call to the IF97 {{{rhovl_p()}}} function, see ticket:4423#comment:16 for more details.

The system is not recognized as linear because the analytical evaluation of the Jacobian fails. It would be worth investigating why that is the case and if it is possible to avoid this failure."	defect	new	high		Backend				Willi Braun
