24 Application
25     stressFemFoam
27 Description
28     Steady-state segregated finite-element solver of linear-elastic,
29     small-strain deformation of a solid body.
31     Simple linear elasticity structural analysis code.
32     Solves for the displacement vector field U, also generating the
33     stress tensor field sigma.
