Weighted residual method

Japanese: 重み付き残差法 - おもみつきざんさほう
Weighted residual method

…As mentioned above, the finite element method divides the internal region of an object into elements, but recently the boundary element method, which divides only the boundary of an object into elements and performs numerical analysis, has been developed and is showing rapid development. In addition, a theoretical system of weighted residuals has been established that can unify numerical analysis methods such as the finite element method and the boundary element method, and it is expected that in the future, any physical phenomenon or material transfer phenomenon described by differential equations will be able to be numerically analyzed under complex boundary conditions using the finite element method or the boundary element method, or by the combination of both. [Yoshiharu Yuki]. …

*Some of the terminology used in reference to the "weighted residual method" is listed below.
