Phase field modeling has become significantly more popular in materials science and engineering and is becoming a mainstream technique. As a result, the growing phase field community continues to develop a wide variety of codes; but it lacks benchmark problems to consistently evaluate, validate, and verify new implementations. Following the example set by the micromagnetics community, the Center for Hierarchical Materials Design (CHiMaD) and the National Institute of Standards and Technology (NIST) are developing benchmark problems that test individual numerical or physical aspects of the codes. We discuss the benchmark problems developed to date, which focus on the diffusion of solute and the growth and coarsening of a second phase, linear elastic solid mechanics, and solidification. We demonstrate the utility of these problems by comparing the results of simulations performed with different numerical techniques. Finally, we discuss the needs of future benchmark problems and how the community can be involved.
