|
|
|
|
Description
|
|
Transient/steady-state segregated finite-volume solver for small strain
|
|
elastic thermal solid bodies. Temperature is solved and then coupled
|
|
displacement is solved.
|
|
|
|
Displacement field U is solved for using a total Lagrangian approach,
|
|
also generating the strain tensor field epsilon and stress tensor
|
|
field sigma and temperature field T.
