    At my partial differential equations homework I found this: boundary conditions: at the spatial province the temperature's perpendicular derivate equal 0.

    What's it mean??

    I have no idea what a "perpendicular derivate" is, if i had to guess it might be that the heat flux at the boundary is zero. (but that's pure guesswork) What is it that the PDE (which i'm guessing is the heat equation) is being applied to?

    Thanks :-)
    It's the 2 dimensional time depending heat equation.
