Summary

This is a stress analysis of a loaded beam in a balanced state. We will fix the region fixedEnd on the left end of the beam, and load (10000, 0, 0) Pa to the region right on the right end of the beam. The calculation is performed as a two-dimensional problem with a single mesh in the Z direction.
