ollowing equations, respectively:

    $$dx = \frac{X}{N-0.5}$$
    $$ \alpha = \frac{k}{\rho * Cp}$$
    $$ Bi = \frac{h*dx}{k}$$
    $$ Fo = \frac{dt* \alpha}{dx^2}$$

    In the first equation, <i>X</i> is the width of and <i>N</i>
    is the number of nodes in a material region of the plate. The other variables are properites of the material.
