3452	Separation of back end transformations for simulation and initialization	Lennart Ochel	Lennart Ochel	"The current back end design is not able to optimize the system for simulation independently from the system for initialization. All the information that are needed to set up the system for initialization is present during the whole optimization process for the simulation DAE. This makes it impossible to do certain simplifications/optimizations on the DAEs.

To gain further improvements, it is necessary to split the transformation pipeline inside the back end to handle simulation and initialization separately."	enhancement	closed	high	1.9.4	Backend		fixed
