INTEGRATION CALCULATION DEVICE OF PRODUCT OF INTERPOLATION FUNCTION IN FINITE ELEMENT METHOD USING TRIANGLE HIGHER ORDER ELEMENT

摘要

PROBLEM TO BE SOLVED: To make each prescribed value calculable just by adding a combination of subscripts by providing a 3rd device which adds together the natural numbers outputted from a 1st and 2nd devices in times equivalent to a specific number of termes of times and a 4th device which calculates each prescribed value from the numeric value of each digit that is outputted from the 3rd device. ;SOLUTION: This device consists of the 1st and 2nd numeric value masters 1 and 2, the 1st to 3rd devices 3 to 5, and a 4th device 6. The master 1 assigns three different types of digit numbers according to the value of α, i.e., the subscript of ϕ of an expression I and also previously stores the natural numbers showing the number of pieces of each of η1, η2 and η3 of an expression II based on the numeric value given to each digit. The device 5 adds together the natural numbers outputted from the device 3 in times equivalent to the term number of ϕ and also outputs the numeric value obtained by adding together the natural numbers outputted from the device 4 in times equivalent to the number of termes of η times. The device 6 calculates the numeric value of 1, m and n respectively from the numeric value of each digit of the numeric value that is outputted from the device 5.;COPYRIGHT: (C)1999,JPO
