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