Selecting Laminar Flow under the Chemical Species Transport>Dispersed Two-Phase Flow with Species Transport branch of the Model Wizard or Add Physics windows, a Mixture Model, Laminar Flow interface along with a Continuous Phase Transport of Diluted Species interface and a Dispersed Phase Transport of Diluted Species interface are added to the Model Builder.

In addition, the Multiphysics node is added, including the multiphysics coupling feature Dispersed Two-Phase Flow, Diluted Species. The Dispersed Two-Phase Flow, Diluted Species feature predefines and controls the couplings between the separate interfaces in order to facilitate easy setup of models.
