The hydraulic conductivity of the soil is a function of the negative pore-water pressure in the unsaturated regions. The rate of change in water content is dependent on the pore-water pressure during transient processes. Hydraulic conductivity can be defined as anisotropic in two orthogonal directions.
The nonlinear nature of the finite element equations is handled using an efficient radial search iterative scheme. Graphing tools are available during run-time to help you judge if convergence has been achieved. This has proved to be extremely useful in solving highly nonlinear flow systems.
AIR/W computes the total flux across single or multiple lines drawn through the mesh.
AIR/W and SEEP/W integrate with TEMP/W so that you can model convective heat transfer due to moving air and water. Conversely, you can have the thermal solution affect the air densities and pressures in AIR/W so that the air will flow based on thermal processes alone. AIR/W passes air content and mass flow vectors to TEMP/W and it returns the new temperature profile to AIR/W. All of this happens automatically based on your analysis type definition.
