ABSTRACT DL_MESO is a highly-scalable general purpose software package for mesoscale modelling. Created and developed at Daresbury Laboratory for the UK Collaborative Computational Project CCP5, it was intended to be a companion package to the flagship molecular dynamics code DL_POLY. One of DL_MESO component codes, DL_MESO_DPD, is based on dissipative particle dynamics, a mesoscale modelling technique with many similarities to classical molecular dynamics. While this code and DL_POLY were created with different applications in mind, they share a significant amount of functionality and development history. This article gives an overview on how DL_MESO_DPD has been developed, including its shared history with DL_POLY and information on its current performance, and a selection of applications for which the code has been used.
