Description
28
Steady-state segregated finite-volume solver of linear-elastic,
29
small-strain deformation of a solid body, with optional thermal
30
diffusion and thermal stresses.
31
32
Simple linear elasticity structural analysis code.
33
Solves for the displacement vector field D, also generating the
34
stress tensor field sigma.
