A lowest order divergence-free finite element on rectangular grids
It is shown that the conforming Q2,1;1,2-Q ′ 1 mixed element is stable, and provides optimal order of approximation for the Stokes equations on rectangular grids. Here Q2,1;1,2 = Q2,1 ×Q1,2 and Q2,1 denotes the space of continuous piecewise-polynomials of degree 2 or less in the x direction but of degree 1 in the y direction. Q′1 is the space of discontinuous bilinear polynomials, with spurious...
متن کاملLogically Rectangular Grids and Finite Volume Methods for PDEs in Circular and Spherical Domains
We describe a class of logically rectangular quadrilateral and hexahedral grids for solving PDEs in circular and spherical domains, including grid mappings for the circle, the surface of the sphere, and the three-dimensional ball. The grids are logically rectangular and the computational domain is a single Cartesian grid. Compared to alternative approaches based on a multiblock data structure o...
متن کاملLinear Systems Arising for Second-Order Mimetic Divergence and Gradient Discretizations
Recent investigations by Castillo and Grone have led to a new method for constructing mimetic discretizations of divergence and gradient operators. Their technique, which employs a matrix formulation to incorporate mimetic constraints, is capable of producing approximations whose order at a grid boundary is equal to that in the grid’s interior. In this paper, we construct a second-order mimetic...
متن کاملConstrained C1 Interpolation on Rectangular Grids
.This paper is concerned with the range restricted interpolation of 'data on rectangular grids. The interpolant is constrained to lie on the same side of the constraint surface as the data. Sufficient non-negativity conditions on the Bezier ordinates are derived to ensure the non-negativity of a bicubic Bezier patch. The method modifies Bezier ordinates locally to fulfill the sufficient non-neg...
متن کاملLogically Rectangular Mixed Methodsfor Groundwater Flow and Transporton
We consider an extended mixed nite element formulation for groundwater ow and transport problems with either a tensor hydraulic conductivity or a tensor dispersion. While the aquifer domain can be geometrically general, in our formulation the computational domain is rectangular. The approximating spaces for the mixed method are deened on a smooth curvilinear grid, obtained by a global mapping o...
