Mesoscale modeling of diffusion in polycrystalline structures

This item was taken from the IEEE Conference ' Mesoscale modeling of diffusion in polycrystalline structures ' We present a new diffusion simulation methodology which has been developed as part of our BackEnd Simulation Tool (BEST) effort. This approach uses the finite element method to address issues critical for modeling polycrystalline materials at the mesoscopic scale. We have included separate grain and grain boundary diffusion, spatially continuous material properties and the concept of equilibrium concentration.
