Potential Surface

This command is used to set the potential surface variable $ps to the specific surface (or directly to the flow directions). Currently included are: Drucker-Prager potential surface, Rounded Mohr-Coulomb (Willam-Warnke) potential surface, von Mises potential surface, Cam-Clay potential surface and Leon potential surface.

set ps "-PotentialSurfaceType <parameter list>"

Valid strings for PotentialSurfaceType are DP, VM and CC.

For the Drucker-Prager potential surface

set ps "-DP"

For the von Mises potential surface

set ps "-VM"

For rounded Mohr-Coulomb (Willam-Warnke) potential surface

set ps "-RMC01"

For the Cam-Clay potential surface

set ps "-CC $M"

$M	Slope of the critical state line in p-q space

For Leon potential surface

set ps "-Leon $fc $ft $e $c"

$fc	compressive strength
$ft	tensile strength
$e	excentricity of yield surface (usually 0.6-0.7)
$c	cohesion
