Details

  • This message is generated when an initial condition includes a derivative of higher differential order than that of the differential equation.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::icord].

Examples

Basic Examples  (2)

An error occurs because the order of the derivative in the initial condition is higher than the order of the highest derivative in the differential equation:

Wolfram Language code: NDSolve[{x''[t] == x[t], x[0] == 0, x'''[0] == 1}, x, {t, 0, 1}]

An error occurs because the differential order of y[t] in the initial conditions is higher than the differential order of y[t] in the differential equation:

Wolfram Language code: NDSolve[{x''[t] + y[t] == 0, y[t] == x[t], x[0] == 1, x'[0] == 0, x''[0] == 0, y[0] == 0, y''[0] == 0}, {x, y}, {t, 0, 1}]
