SOLUTION: In input of divided objective data, objective data is divided into elements, and objective face data for finding an electric current and a magnetic current in each element and pattern data formed on a printed board are inputted, and then, the divided data are inputted. In this process, the dividing size and the dividing number of the face data are inputted for inputting partially divided data, and a dividing process is carried out. Then, simultaneous equations are formed about each divided element and calculation is carried out for finding an electric current and a magnetic current flowing through each element. In this way, the divided objective data 6, 7 and the division information are inputted so as to automatically divide a pattern part indicated by pattern data 7 into fine elements, the divided elements are gathered together as a single group of elements as a whole, and then, the simultaneous equations are formed for calculating an electric current and a magnetic current in each element, and consequently, the results can be displayed while correlated with the respective elements.
