These capabilities are available for any supported physics interface, such as structural mechanics, heat transfer, CFD, AC/DC, and RF applications.

      In this minicourse, we will provide an overview of the available optimization methods in COMSOL Multiphysics® and demonstrate how to set up and solve optimization studies.

    • COMSOL Multiphysics® and its add-on products provide specialized functionality for modeling and simulation of fluid flow. The CFD Module enables the analysis of laminar and turbulent flows for the design and optimization of processes and devices, while additional add-on products extend these capabilities to flow in porous and fractured materials.

Modeling options include a wide range of turbulence models, high-Mach-number flows, non-Newtonian flows, and fluid flow in porous media.

      In this session, we will demonstrate how to model flow in a 40-meter-long water treatment basin with baffles that generate turbulence along the flow path.

    • Modeling species transport and chemical reactions can lead to improved understanding and optimization of reacting systems. The Chemical Reaction Engineering Module, an add-on product to the COMSOL Multiphysics® software, was designed to mimic the experimental procedure in a lab using the following comprehensive modeling strategy: study kinetics in a perfectly mixed system; use accurate thermodynamic properties of both species and mixtures; then, create a space-dependent model using those reaction kinetics to study transport and reaction processes.

      The Chemical Reaction Engineering Module can also be combined with the add-on CFD Module to study turbulent nonisothermal reacting flow and turbulent multiphase flow. Turbulence modeling is offered by a wide range of Reynolds-averaged Navier–Stokes (RANS) models, as well as large eddy simulation (LES) and detached eddy simulation (DES).

      In this session, we will demonstrate how to set up a model from scratch using chemical equations in a perfectly mixed system. We will then use the functionality for automatically creating space-dependent models to account for transport phenomena, including chemical species transport, fluid flow, and heat transfer.
