Advantages of Passage DEM+FLOW

By coupling PASSAGE: Discrete Element Modeling (DEM) and 3D FLOW software a variety of problems can be solved which can not be treated by using either one model individually. This capability allows modeling of liquids, gases, solid particles and their mixtures for many industrial problems in both micro and macro scales. It can be applied to process modeling of mixing, wetting, coating, filtration, fermentation and filling operations for applications in food, pharmaceutical, chemical, metals, plastics, glass, ceramics, powders processing and emission control. 

DEM and FLOW modules can be coupled in a variety of ways depending on the application.
