The Initial Values node adds initial values for the velocity potential. For The Linearized Potential Flow, Transient Interface it also adds initial values for the velocity potential, first time derivative. If needed, add more Initial Values nodes from the Physics toolbar or the main physics interface node’s context menu.

Enter a value or expression for the initial value of the Velocity potential phi (SI unit: m2/s).

For The Linearized Potential Flow, Transient Interface also enter a Velocity potential, first time derivative, (SI unit: m2/s2).
