The heat equation requires only the initial value to solve the equation. However, for the wave equation, specify the value and the derivative value with respect to the time variable at initial time. The following block diagram is an example of how to define the initial condition for a one-dimensional wave equation. The VI defines the initial value, and the numeric array defines the initial derivative.
