An illustration of three-dimensional finite difference simulation of heat conduction with phase change and complex boundary conditions, this requires students to adjust boundary conditions to make the top surface of a regular hexahedral "casting" to freeze last, eliminating macroporosity.
Requisite software: castabox, which in turn requires Illuminator, PETSc and Geomview, all open source.
Assignment solution time: 1 hour
