DSolve::derlen NDSolve::derlen NDSolveValue::derlen ParametricNDSolve::derlen ParametricNDSolveValue::derlen

Details

This message is generated when the number of independent variables does not match the number of arguments in the solution function in the specification of the equations.
Off[message] switches off the message; On[message] switches it on. For example: Off[DSolve::derlen].

Examples

Three variables are specified in the third argument, suggesting that the input may represent a partial differential equation:

Wolfram Language code: DSolve[{f'[x] == f[x], f[1] == 1}, f, {x, y, z}]

Avoid the error message by specifying only x in the third argument:

Wolfram Language code: DSolve[{f'[x] == f[x], f[1] == 1}, f, {x}]
