Abstract
A complete inverse problem is formulated by coupling the inverse finite element heat transfer simulation module with an inverse MC grain growth simulation module. Given the target grain size distribution in the film, the historical current in the heater lines of the micro-heater array is solved by driving the two modules. Specifically, the grain size distribution is measured in the MC simulation and it is used to update target temperature distribution for the inverse heat transfer simulation to solve for, and the corresponding current input is updated. This inverse problem is solved and scaled on the RPI super computer IBM Blue Gene Q. Performance of parallelization is investigated and discussed.
