SmoothnessEstimator Namespace Reference



Detailed Description

A namespace for various smoothness estimation strategies for hp-adaptive FEM.

Smoothness estimation is one strategy to decide whether a cell with a large error estimate should undergo h- or p-refinement. Typical strategies decide to increase the polynomial degree on a cell if the solution is particularly smooth, whereas one would refine the mesh if the solution on the cell is singular, has kinks in some derivative, or is otherwise not particularly smooth. All of these strategies rely on a way to identify how "smooth" a function is on a given cell.
