WebSep 6, 2013 · The Galerkin finite element method of lines is one of the most popular and powerful numerical techniques for solving transient partial differential equations of parabolic type. The Galerkin finite element method of lines can be viewed as a separation-of-variables technique combined with a weak finite element formulation to discretize the … WebHere for instance, you can take ϕj(x) = sin((2j + 1)πx / 2). Write hj(x, tn) = ∑jcj(tn)ϕj(x). As I am not familiar with the Galerkin method, you should take this with a grain of salt. This might not be the correct or the most efficient way to deal with your BC.

WebThe Galerkin scheme is essentially a method of undetermined coefficients. One has n unknown basis coefficients, uj, j = 1,...,n and generates n equations by successively … WebMay 17, 2024 · Abstract In this paper, we propose a new numerical scheme for the coupled Stokes-Darcy model with the Beavers-Joseph-Saffman interface condition. We use the weak Galerkin method to discretize the Stokes equation and the mixed finite element method to discretize the Darcy equation. homemark leather repair kit
