Analysis Type(s): Thermal Analysis (with phase change) (ANTYPE = 4) Element Type(s): 2-D Thermal Solid Elements (PLANE55) Input Listing: vm104.dat Test Case A layer of liquid (of depth a), covering an insulated surface and initially at its freezing temperature To, is suddenly subjected to a free surface temperature Ts (less than To). Determine the time, tf, taken for the liquid to solidify completely, and the temperature distribution in the solid phase at time t1 seconds.
