Initial Values
The Initial Values node adds an initial value for the pressure, pressure head, or hydraulic head pressure that can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear solver.
Initial Values
•
Select the Pressure (the default) button to enter a value or expression for the initial value of the pressure p (SI unit: Pa). The default is 0 Pa.
•
Select Pressure head to enter a value or expression for Hp (SI unit: m).
•
Select Hydraulic head to enter a value or expression for H (SI unit: m).
