Detailed Description

Variable Documentation

darcy_anisotropic_dispersion

integer darcy_anisotropic_dispersion

Set dispersion to isotropic (0) or anisotropic (1) for all solutes

darcy_anisotropic_permeability

integer darcy_anisotropic_permeability

Set permeability to isotropic (0) or anisotropic (1) for all soils

darcy_convergence_criterion

integer darcy_convergence_criterion

Set convergence criteron of the Newton scheme

• 0: over pressure (recommanded)
• 1: over velocity

darcy_gravity

integer darcy_gravity

Set gravity to compute the pressure head from the hydraulic head and the elevation ( is the elevation by default). Only used in the Van Genuchten model. If enabled the pressure head is stored in field of index iprtot. The reference elevation is always the elevation of point (0,0,0).

darcy_gravity_x

double precision darcy_gravity_x

Darcy gravity direction x component. Gravity direction must be a unit vector.

darcy_gravity_y

double precision darcy_gravity_y

Darcy gravity direction y component. Gravity direction must be a unit vector.

darcy_gravity_z

double precision darcy_gravity_z

Darcy gravity direction z component. Gravity direction must be a unit vector.

darcy_unsaturated

integer darcy_unsaturated

Take into account unsaturated zone (1) or not (0).

darcy_unsteady

integer darcy_unsteady

Set if the transport part is based on a steady (0) or unsteady (1) flow field
