- Since 'bool' and 'Switch' use the _identical_ input mechanism (ie, both accept true/false, on/off, yes/no, none, 1/0), the main reason to prefer one or the other is the output. The output for Switch is as text (eg, "true"), whereas for bool it is label (0 or 1). If the output is required for a dictionary, Switch may be appropriate. If the output is not required, or is only used for Pstream exchange, bool can be more appropriate.

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.
