stressFemFoam
|
|
|
|
Description
|
|
Steady-state segregated finite-element solver of linear-elastic,
|
|
small-strain deformation of a solid body.
|
|
|
|
Simple linear elasticity structural analysis code.
|
|
Solves for the displacement vector field U, also generating the
|
|
stress tensor field sigma.
