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.
