NDSolve::jpde NDSolveValue::jpde ParametricNDSolve::jpde ParametricNDSolveValue::jpde

Details

This message is generated by an inconsistent specification of whether the Jacobian should be computed symbolically or numerically.
Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::jpde].

Examples

A warning message is generated because the specified value of the Jacobian option will not be used:

Wolfram Language code:

NDSolve[{D[u[x, t], t] == D[u[x, t], x, x], u[x, 0] == Exp[-100 x ^ 2], u[-1, t] == u[1, t]}, u, {x, -1, 1}, {t, 2}, Jacobian -> "Symbolic"]

This shows a correct input:

Wolfram Language code: NDSolve[{D[u[x, t], t] == D[u[x, t], x, x], u[x, 0] == Exp[-100 x ^ 2], u[-1, t] == u[1, t]}, u, {x, -1, 1}, {t, 2}]
