The differential equation of the problem is D(U)=0 on the boundary … WebGalerkin method is also related to the standard mixed ﬁnite element method in that the two methods are identical for simple model problems (such as the Poisson prob-lem) using certain ﬁnite element discretizations (for example, Raviart-Thomas [27] ... robustness of the weak Galerkin method with numerical examples. Once a standard WebGalerkin Method Weighted residual methods A weighted residual method uses a finite number of functions . The differential equation of the problem is D(U)=0 on the boundary B(U), for example: on B[U]=[a,b]. where “L” is a differential operator and “f” is a given function.
