WebGalerkin Method was generalised to the Galerkin FEM. Galerkin’s method1 is one of a number of numerical techniques known as Weighted Residual Methods. These various weighted residual methods are often as effective as each other, but it is the Galerkin method which leads naturally into the Finite Element 1 Boris Grigoryevich Galerkin was … Websurvey line is treated in this work. Following the Galerkin method, we used finite element discretization along the depth direction and the FD method in the spatial domain to solve partial differential equations, which has been clearly addressed by Du and Bancroft (2004). In previous work, we tested the effect of the new method on a regular mesh. timthriall https://accenttraining.net
