I am a relative newbie to FlexPDE. I have done some thermal modeling using this software but never tried such a complicated problem. At this point, I'd just assume a very simple shape such as a cube of aluminum. I'm heating the center of one face of this cube with a high power laser. Assume I know the following: 1) Conductivity of aluminum as a function of temperature 2) Absorption coefficient of the aluminum to the laser light as a function of temperature 3) Power and size of the round beam of my laser 4) Heat of melting (fusion) of aluminum I can do the problem for time dependent rise in temperature up to the point that a certain volume reaches the melting point. At that point, the temperature doesn't rise until a certain extra amount of heat is deposited which requires a certain amount of extra time where the temperature doesn't rise. I have no idea if FlexPDE can handle such a discontinuity once the material reaches the melting point. Any ideas ? | ||

The example problem "Samples|Time_Dependent|Chemistry|Melting.pde" solves a phase-change problem. Take a look at that script and see if you can adapt it. |
