Until recently, the use of a phase field model to simulate dislocation mediated plasticity was applied only to cubic crystallographic materials. We present enhancements to the phase field dislocation dynamics formulation in order to consider hexagonal close packed metals. The enhancements are directly informed with density functional theory and allow the model to consider slip-mode dependent energetics and their influence on dislocation behavior. We present results for multiple slip modes active in hcp metals.
