# Bracket

This example employs adaptive multimesh hp-FEM to solve equations of linear elasticity.

## Problem description

Our domain is a bracket loaded on its top edge and fixed to the wall:

The dimensions are L = 0.7 m, T = 0.1 m and the force N.

## Sample results

The following figures show the two meshes and their polynomial
degrees after several adaptive steps:

Note that the meshes are slightly different, not only in
polynomial degrees, but also in element refinements.

## Convergence comparison

Convergence graphs of adaptive h-FEM with linear elements, h-FEM with quadratic elements
and hp-FEM are shown below.

The following graph shows convergence in terms of CPU time.
