WebAnsys CFX and Ansys Fluent, one of famous commercial CFD software packages, is based on a finite volume method approach. These codes differ mainly in the way they integrate fluid flow equations and in their equation solution strategies. Ansys CFX solver uses cell-vertex finite volumes to discretize the domain. WebApr 11, 2024 · The spectral/hp element method combines the geometric flexibility of the classical h-type finite element technique with the desirable numerical properties of spectral methods, employing high-degree piecewise polynomial basis functions on coarse finite element-type meshes. The spatial approximation is based upon orthogonal polynomials, … WebThere are different methods to discretize the complex governing equations, called discretization methods. A few popular discretization methods utilized in CFD tools are the finite element method, finite volume method, and finite difference method. We will take a deep dive into the finite difference method in the upcoming section. spokane wa pest control
