A Multiscale Finite-Element-Method

Civil-Comp Proceedings, 1997
Abstract This paper describes a hierarchical overlay of a p -version finite element approximation on a coarse mesh and an h -approximation on a geometrically independent fine mesh. The length scales of the local problem may be some orders of magnitude below the scale of the global problem.

Curved Elements in the Finite Element Method. II

SIAM Journal on Numerical Analysis, 1973
Curved elements, introduced by the author in [13] and [14], which are suitable for solving boundary value problems of the second order in plane domains with an arbitrary boundary are discussed. An approximation theorem is proved, the Dirichlet problem for a ${\mathop W\limits^{\circ}} _2^{(1)} $-elliptic equation is considered as a model problem and ...

An Introduction to Finite Element Methods

Proceedings of the 2015 ACM International Symposium on Symbolic and Algebraic Computation, 2015
The most common techniques for obtaining numerical solutions to partial differential equations on non-trivial domains are (high order) finite element methods. The given domain is subdivided into simple geometric objects and an approximate solution is computed as a linear combination of locally supported basis functions.

Finite-Element Methods

2002
The finite-difference approach with equidistant grids is easy to understand and straightforward to implement. The resulting uniform rectangular grids are comfortable, but in many applications not flexible enough. Steep gradients of the solution require a finer grid such that the difference quotients provide good approximations of the differentials.
