+Previous versions of EMSO support only a few common options for the solvers, such as '''relativeAccuracy''' and '''absoluteAccuracy'''. However, each solver has its own specific design options.

+Now besides common options, there are solver specific options declared as follows:

 Other suggestion for the '''OPTIONS''' section is to tell the simulator to use the steady-state solution as initial condition for the dynamic simulation. In this case the NLP for the initialization is not necessary, because all derivatives are set to zero. A suggestion to set this option could be using the '''InitialFile''':
