For clarification purposes, it should be noted that the initial temperature (Ti) term in the Neumann solution is expressed as the number of degrees below 0°C (i.e. it is a positive number). |

- | {{ : | + | The initially uniform temperature is at 0°C. This condition simplifies the energy balance at the thawing front by ensuring that there is no thermal gradient (or conductive flux) below the thawing front. The specified surface temperature is above 0°C and hence induces thaw. The water is advected through the entire medium, but the divergence of the advective flux is zero below the thawing front due to the uniform thermal conditions. |
