Detailed Description

Variable Documentation

integer darcy_anisotropic_dispersion

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

integer darcy_anisotropic_permeability

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

integer darcy_convergence_criterion

Set convergence criteron of the Newton scheme

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

Set gravity to compute the pressure head $ h $ from the hydraulic head $ H $ and the elevation ( $ z $ 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).

double precision darcy_gravity_x

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

double precision darcy_gravity_y

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

double precision darcy_gravity_z

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

integer darcy_unsteady

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