Abstract
An extremely high-speed, very stable system and a method for concurrent computing between heterogeneous simulators are shown, in which heterogeneous simulators for analyzing a complicated physical phenomenon are coupled based on a coupled equation thereby to obviate the disadvantages of the conventional noncoupled and coupled methods. A numerical calculation unit includes a calculation control unit equipped with an agent function having a heterogeneous coupling variational equation calculation unit, a convergence decision unit and a search vector setting unit. A parameter and a variable are supplied from the heterogeneous coupling variational equation calculation unit into and out of a simulator A, a simulator B and a heterogeneous coupled equation thereby to form the heterogeneous coupling variational equation 1 and thus to determine a globally consistent solution. With this configuration, a globally consistent solution can be obtained automatically simply by setting a heterogeneous coupled equation, and therefore the analysis and design efforts of an operator can be very effectively supported in analyzing complicated physical phenomena in all the fields of advanced science and technologies.
