摘要

PROBLEM TO BE SOLVED: To shorten simulation time by generating an initial vector capable of reducing iteration frequency required up to the solution of simultaneous linear equations. ;SOLUTION: A connection contact weight information processing part 1 finds out the weight of each contact from contact connection information stored in a contact connection information storing part and contact coordinates stored in a contact coordinate storing part by using a weight calculation part and stores the weight in a connection contact weight information storing part. An interpolation calculation part stores an interpolation result in each component based on time stored in a time storing part, a vector stored in a vector storing part and time inputted to a time input part in the vector storing part. A weight addition part stores a correcting calculation result based on the vectors stored in the vector storing part, the weight set of contacts stored in the connection contact weight information storing part, an acceleration coefficient stored in an acceleration coefficient storing part 4, and contact connection information stored in the contact connection information storing part 12 in the vector storing part. An iteration method calculation part 9 finds out a solution by using a coefficient matrix inputted to a coefficient matrix input part 7, a right side vector inputted to a right side vector input part 8 and an initial vector stored in the vector storing part.;COPYRIGHT: (C)2000,JPO
