Unlike a finite element method, in which computing is performed by digitizing, a continuous functional form of physically appropriate deflection is supposed to find an unknown coefficient of a functional form by Ritzmethod, whereby the computing amount can be remarkably reduced so as to achieve future estimation of turbines of global-scale variety at high speed. 有限要素法と異なり、離散化して計算するのではなく、物理的に妥当な撓みの連続関数形を仮定し、Ritz法により関数形の未知係数を求めるので、計算量が格段に削減され、地球規模的に多様であるタービンの将来予測を高速に行うことができる。 - 特許庁
