May 23, 2008 · Modeling differential equations require initial conditions for the states in order to simulate. The initial states are set in the integrator blocks. Think of these as the initial value for v and x at time 0. The ODE solvers compute the derivatives at time zero using these initial conditions and then propagate the system forward in time.

Choose an ODE Solver Ordinary Differential Equations. An ordinary differential equation (ODE) contains one or more derivatives of a dependent variable, y, with respect to a single independent variable, t, usually referred to as time.The notation used here for representing derivatives of y with respect to t is y ' for a first derivative, y ' ' for a second derivative, and so on.
