| Abstract: |
|---|
| It is well known that the discretization of a finite element method
results in a linear system of equations, in which the matrix and the load
vector are usually computed by numerical integration. The inexact integration
may lead to a different linear system, and consequently, produce a different
finite element solution. In this talk, we will first discuss the existing
results on the impact of quadrature rules on the finite element approximation
in the energy norm. Then, a sharp estimate on the convergence rate of the
finite element approximation with numerical integration for linear functionals
will be presented. |
