A New Approach to FEM for Non-Polygonal Domains
Martin Licht
UCSD
Abstract:
We discuss a new approach to finite element methods for partial differential equations (PDEs) over non-polyhedral domains. We transform PDEs from a physical domain to analogous PDEs over a parametric domain. The transformed PDE generally involves smooth coefficients, whose approximation leads to a variational crime in the finite element method. Only recent results in approximation confirm optimal error estimates. We also point out some gaps in the literature. We present examples from computational physics.
