 it can be tried to restart the simulation from a formerly stored FMU state by calling `fmi2SetFMUstate`.
 This can be done if the capability flag `canGetAndSetFMUstate` is true and
 `fmi2GetFMUstate` was called before in non-erroneous state.
+It is also possible to reset the instance of the FMU by calling `fmi2Reset`.
 footnote:[Typically, `fmi2Error` return is for non-numerical reasons, like "disk full".
