About the Microfluidics Module

The Microfluidics Module is a collection of tailored physics interfaces for the simulation of microfluidic devices. It has a range of tools to address the specific challenges of modeling micro- and nanoscale flows.

Physics interfaces that address laminar flow, multiphase flow, flow in porous media, and moderately rarefied flow (the Slip Flow interface) are available. Enhanced capabilities to treat chemical reactions between dilute species are also included. COMSOL Multiphysics also has tools to model the transport and reactions of concentrated species, but the Chemical Reaction Engineering Module is required for these physics interfaces. In addition to the standard tools for modeling fluid flow, interfaces between fluids can be modeled by the Level Set, Phase Field in Fluids, and Moving Mesh interfaces, making it possible to model surface tension and multiphase flow at the microscale.

The Microfluidics Module Application Library and supporting documentation explain how to use the physics interfaces to model a range of microfluidic devices.
