I probably have a physics problem here, and not a FlexPDE problem per se. By any chance does somebody here know how to make this right? And the inclination?

Revised version gives me an error, "Operands are not of same type", and highlights the div operator on the second Equation. I don't understand this error. This div operator is very similar to the div operator in the first Equation which does not produce that error message.
