Patent ID: 7490029

Claim:
A computer-implemented method for simulating operation of a physical system having a plurality of physical subsystems, comprising: simulating a first physical subsystem with a first continuous-time simulation on a first physical computing device; accepting a request for export of information relating to a number n of state-related variables that characterize the state of the first physical subsystem in said simulating; sending a first series of state-related messages, each message containing information relating to the value of at least one of the n state-related variables; simulating a second physical subsystem with a second continuous-time simulation on a second physical computing device; receiving in said second continuous-time simulation said first series of state-related messages from said first continuous-time simulation without said first series of state-related messages passing through a central communication process; and outputting data representative of a state of the second continuous-time simulation; wherein: the first physical subsystem interacts with the second physical subsystem; and the at least one state-related variable characterizes at least a portion of the interaction between the first physical subsystem and the second physical subsystem.
