Web1 Aug 2024 · The Petrov–Galerkin method is a mathematical method used to approximate solutions of partial differential equations which contain terms with odd order and where the test function and solution function belong to different function spaces. It can be viewed as an extension of Bubnov-Galerkin method where the bases of test functions and solution … WebA popular approach to combat this is the streamline upwind Petrov-Galerkin discretization. Suppose that the advection is along a vector field w, and let ϕ n be a basis function. The test function ψ n is then defined in terms of the basis function and the advection field as ψ n = ϕ n + α w ⋅ ∇ ϕ n, where α is an appropriately-selected parameter.
