RaviartThomas
Raviart-Thomas elements are a family of finite element spaces used in the numerical solution of partial differential equations, particularly in the context of vector fields. They were introduced by Pierre Raviart and Jean-Pierre Thomas in 1977. These elements are particularly useful for solving problems involving vector fields, such as the Stokes equations, which describe the flow of viscous fluids.
Raviart-Thomas elements are defined on simplicial meshes, typically triangles in two dimensions and tetrahedra in three
The Raviart-Thomas spaces are polynomial spaces of degree k, denoted as RTk, where k is a non-negative
One of the key properties of Raviart-Thomas elements is their ability to represent the divergence of vector
In summary, Raviart-Thomas elements are a powerful tool in the finite element method for solving problems involving
