Parameter definition

VariableDescription
coid Sub-domain ID
type Air type
options:
AIR $\rightarrow$ air at 1atm and 293K
VOID $\rightarrow$ vacuum
USER $\rightarrow$ user defined
gid Geometry ID
$t_{end}$ Particle deactivation time or FUNCTION (fcn)
options: time or fcn
default: not used
$\rho_0$ Density (this line is only used if type=USER)
$e_0$ Energy per unit volume
$\gamma$ Fraction between C${}_\mathrm{p}$ and C${}_\mathrm{v}$
$v$ Co-volume at $\rho = \rho_0$

Description

Discrete particle air domain definition.

The command id (coid) determines in which order particles are filled into the global domain. In case sub-domains are overlapping, the domain with the largest ID will overwrite (remove) particles belonging to domains with lower domain ID's.
