#  This file can be run to check that the melting in simple conduction is correctly modeled.

#  There is no velocity (no advection) the only thermal boundary conditions are an imposed temperature

#  at upper surface and an impose flux at its base. The result must be a linear temperature from the upper to the lower

#  surface with an imposed slope (Geothermal flux). if it is not the case, something is thermal modeling has been changed...
