The Initial Values node adds an initial value for the pressure that can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear solver.
The Shell Properties settings can only be edited if the
Initial Values node was added manually. For the default node, the same settings as in the
Shell Properties section of the parent interface are applied.
If you clear the Use all layers checkbox, you can select individual layers within one layered material. If you need to specify different initial values for different layered materials or for different layers, you have to add one
Initial Values node for each layered material or for each layer.
In case the Subsurface Flow Module is licensed, click the Pressure head button to enter a value or expression for
Hp (SI unit: m). The default is 0 m. Click the
Hydraulic head button to enter a value or expression for
H (SI unit: m). The default is 0 m.
