Two or more solvers used in a simulation of a dynamic system may exchange information during minor steps of at least one of the solvers. The information may be exchanged one way—that is, a first solver sending the information to a second solver after the second solver's minor step, or it may be exchanged two ways (or multiple ways in a case with more than two solvers). If the solvers are instances of the same type of solver, they may exchange information at each minor step.
