COMSOL Releases Multiphysics 4.4

Latest simulation software package includes upgrades to UI, CFD, and Mixing analysis

COMSOL  just announced the release of their Multiphysics 4.4 environment known for its mechanical, electrical, fluid, and chemical applications.

The biggest cosmetic difference in the software is the addition of the ribbon made famous by the Microsoft Office programs. Though not a fan of these ribbons myself, COMSOL’s CTO, Ed Fontes believes that, “[the] ribbon provides users with a clear picture of the workflow of the modeling process, helping them to quickly and easily determine the functionality that is available for each of the steps involved.” Commands are grouped and positions based on their task and within the various tabs (geometry, definitions, mesh, physics, study, and results).

Another noted environment addition is the use of one-click graphic selection. By hovering over a feature, it will highlight. The feature can then be selected by clicking on it.

Multiphysics 4.4 also includes an auto-complete search that can help users find the variable needed for multiphysics models. These models can then be applied to new Multiphysics nodes for quick setup.

COMSOL’s VP of Product Management Bjorn Sjodin notes that, “[the] Multiphysics node gives you a comprehensive overview of the available couplings in your model. You can then control how to account for multiphysics phenomena by deciding how the physics included in your simulation interact with one another.”


Mixer module simulates thermal flows in a non-adiabatic system.

New to the system is a Mixer module that is intended to analyze industrial mixers used in the pharma, food, and chemical industries. The Mixer module can simulate impeller design, concentrations, velocities, and temperature distribution.

There are also some big improvements to the CFD module in COMSOL 4.4 so it can now handle turbulent/laminar flows, Newtonian/non-Newtonian fluids, free-surface, reacting, and non-adiabatic flows.
