PURPOSE:To shorten the time required to obtain a parameter value giving the required distribution by calculating the function characteristic distribution of an object including the fluctuation parameter by the specified method and solving the equation giving the equivalence to the required distribution. CONSTITUTION:The fluctuation parameters r1-rn (n>=1) such as material values describing the coordinate value describing the form and the nature of material are inputted to a calculation means (code arithmetic type SOLVER) of the boundary element method or the limited element method. The arithmetic operation is performed on code by the machine language such as mathematica and the calculation value yk=fk (r1-rn) of the function characteristic distribution (field) is outputted. The k represents the number of the space coordinate point to calculate the function characteristic distribution and k>=1. With an unknown factor, the approximate formula by the series development formula is obtained and the variable is represented by the approximate formula. The calculated function characteristic distribution and the required function characteristic distribution are requalled to prepare the equation including the variables. By solving the equation, the parameter realizing the required function characteristic distribution is controlled or decided. |
