Automatic time substep sizing will vary substeps between the extremes. A Table Array is used for the time-dependent Convection Coefficient values. Times go in the Zeroth column, while associated Convection Coefficients go in the First column. A hard copy X-Y figure of the table is plotted at the end: !

In numerical analysis and scientific computing, the backward Euler method (or implicit Euler method) is one of the most basic numerical methods for the solution of ordinary differential equations. It is similar to the (standard) Euler method, but differs in that it is an implicit method. The backward Euler method has error of order one in time.
