Structure to handle the modelling of a single-phase flows in a porous media considered as saturated.
Several simplifications are operated in this context. Only the liquid phase is taken into account. Several properties are constants.
| darcy |
Pointer to a cs_gwf_darcy_flux_t structure. Darcy advective flux in the liquid phase. This structure is used to define the advective term in tracer equations.
| moisture_content |
This quantity describes the level of saturation in a soil. This is a constant value in case of a satured soil.
| pressure_head |
Pointer to a cs_field_t structure. Allocated only if the gravitation effect is active. Location of this field depends on the discretization scheme used to solve the Richards equation. The pressure head is denoted by h, hydraulic head (unknowns solved in the Richards eq.) is denoted by H and there are linked by: h = H - gravity_potential
| richards |
The Richards equation is the governing equation which corresponds to the mass conservation of water. "hydraulic_head" is the associated variable "permeability" is the diffusion property related to this equation.
