Details

  • This message is generated when the function arguments in the specification of an equation occur in different orders in different parts of the equation.
  • The cause of this error can in most cases be readily identified by inspecting the input to be sure that the solution function is always specified in the same way.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[DSolve::conarg].

The arguments of the solution function are not ordered consistently:

This shows a correct specification of the partial differential equation:

Dependent variables need to be grouped together:

In the list of variables, and are not grouped together. It should be written as :
