4246	Make the documentation of Integration Methods consistent and up-to-date	Francesco Casella	Willi Braun	"The online documentation on solver methods available here
  https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/simulationflags.html#simflag-s

is too concise and inhomogeneous. In particular, for many algorithms it is not clear whether they do have error control and step-size/order adaptation or not.

Some more information is provided in another section of that document

https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/simulationflags.html#integration-methods

but only for some of the algorithms, and I am not sure it is up-to-date even for those ones. Overall, this is sometimes frustrating, and gives a bad impression about the software quality

I would suggest the following actions
- make the information displayed under the -s=value section consistent w.r.t. the solver being fixed- or variable-step-size, i.e. either always mention this info, or never mention it
- add a link to the detailed description to the -s=value text, e.g. ""Value specifies the integration method. See <Integration Methods> for additional details""
- update and complete the information shown in the Integration Methods section of the documentation, including a description of all the supported methods"	enhancement	closed	blocker	1.13.0	Documentation		fixed
