  • Co-simulation procedures using full derivatives of output variables
    Patent number: 9223754
    Abstract: A computer-implemented method for use in simulating dynamic behavior of complex engineering systems comprised of several subsystems includes computing a Jacobian matrix based on output derivatives, wherein the output derivatives are based on corresponding state variable derivatives related to corresponding first input variables for each of a plurality of subsystems. The method also includes modifying the first input variables and computing second input variables and residuals for each of the plurality of subsystems based on corresponding state variable derivatives.
    Type: Grant
    Filed: June 29, 2012
    Date of Patent: December 29, 2015
    Assignee: Dassault Systèmes, S.A.
    Inventors: Vladimir Belsky, Bruce Edward Engelmann, Hilding Elmqvist, Hans Roland Olsson
