Abstract Scope Phase field modeling is becoming a mainstream technique in materials science and engineering and is often the mesoscale modeling component of integrated computational materials engineering (ICME) materials design strategies. New numerical approaches have been developed over the years to tackle different phase field models, but until now the community has lacked standard problems to consistently evaluate these methods. The Center for Hierarchical Materials Design (CHiMaD) and the National Institute of Standards and Technology (NIST) are developing benchmark problems focusing on targeted aspects of the physics of phase transformations for numerical verification. We discuss the set of problems developed to date, present example comparisons of simulations performed with different numerical techniques, and describe how the problems are being used within the phase field community. Finally, we discuss our plans for deriving additional numerical verification problems as well as considerations for creating experimental data sets for model validation.
