Parameter definition
Variable | Description |
---|---|
sid | Subdomain ID |
type | Soil type |
gid | Geometry ID |
$dsf$ | Particle density scale factor (particles per unit volume) |
$t_{end}$ | Particle deactivation time or FUNCTION (fcn) |
$\rho_0$ | Density (this line is only used if type=USER) |
$k$ | Grain contact stiffness |
$\mu$ | Grain contact coefficient of friction |
$\xi$ | Grain contact damping coefficient |
$v$ | Fill fraction (typically between 0.58 and 0.62) |
$\eta$ | Dimensionless shear cap coefficient |
Description
Discrete particle soil domain definition.
The subdomain ID (sid) determines in which order particles are filled into the global domain. In case subdomains are overlapping, the domain with the largest ID will overwrite (remove) particles belonging to domains with lower domain ID's.
