Abstract:
1. A computer implemented method in a simulation of a physical system, wherein the system is described by a first set of n simultaneous linear algebraic equations and is simulated by a second system described by a second set of n simultaneous linear algebraic equations, each of said equations being of a form: wherein x j are n unknowns, e ij are n coefficients for each of the n equations of each set, and b i are n quantities, said coefficients and quantities being known algebraic expressions, said method comprising the steps of: a) providing respective reduced sets, wherein step a) includes the following substeps for each of the equations of each of the sets: b) combining and rearranging terms resulting from substeps a1) through a6) to eliminate said unknowns from each of said sets of simultaneous linear algebraic equations and to provide for each set, n equations in a form: wherein l c) comparing, using a processor, for each of said unknowns, a first product (l
