Recent advances in and applications of the public domain Object Oriented Finite Element software for Materials Science (OOF) are discussed. The OOF software calculates the macroscopic properties from two-dimensional microstructures. It operates directly from microstruc- tural image data to create a computational model that has the same spatial properties as the two-dimensional material microstructure. Recent progress in the code accounts for applied continuum thermal, electrostatic, elastic and chemical potential fields and how they are lo- cally coupled through properties at a microstructural level. We illustrate the application of the software by computing the macroscopic properties of polycrystalline piezoelectrics. We also demonstrate the effect of microstructure on the response of a porous cathode in a rechargeable lithium ion battery and calculate the resulting chemically induced (Vegard) stresses. We also discuss the impending public release of the OOF2 code, which allows the user to simulate nearly arbitrary sets of applied fields and nearly arbitrary material constitutive equations in microstructures, using an intuitive graphical interface.
