要約: front page image
Task: To provide a method for synthesizing numerical operators, a system for synthesizing operators, and a simulation device, which can appropriately realize stability in addition to computational efficiency and optimal accuracy in a numerical analysis of wave motion in a finite region of an elastic body which is carried out using a time-domain finite-difference scheme. Means for Resolution: A stiffness matrix H' is designed as PiTCPi or a linear combination form thereof, where a spatial first-order difference operator, which operates on a state vector, of a displacement vector at each discrete grid point is Pi and the matrix of elastic constants is C. The mass matrix T' is derived using finite-difference approximations at the discrete grid points so that the result of the matrix δTnum operating on a state vector corresponding to rotations or translations is 0, where T is a positive definite diagonal mass matrix and δTnum = T'-T.
