New User Interface with Ribbon Design and Multiphysics Node
One of the most noticeable changes in COMSOL Multiphysics 4.4 is the updated user interface (UI), which features a ribbon design and a new Multiphysics node. The ribbon UI provides a clearer overview of your workflow and makes it easier to find the commands and operations you need to set up your models and run your simulations. The ribbon only displays the relevant commands for each step of the modeling process, such as geometry, physics, mesh, study, and results.
The new Multiphysics node gives you more control over the couplings between different physics phenomena in your models. For example, you can easily define thermal stress and electromagnetic thermal effects using the Multiphysics node. You can also customize the couplings by adding or removing terms, changing signs, or modifying coefficients.
The new UI also includes other improvements, such as a new hover-and-click selection method, an auto-complete search tool for variables, user-defined geometric primitives, if/else statements in the model tree for conditional geometry creation, NASTRAN-mesh file export, and time-unit handling in the solvers.

Functionality Enhancements Across the Product Suite
In addition to the new UI, COMSOL Multiphysics 4.4 also offers many functionality enhancements across the existing products. Here are some of the highlights:
The CFD Module includes a new boundary condition for modeling wall roughness for turbulent flow and an Outlet boundary condition for more accurate and robust laminar flow simulations.
The Heat Transfer Module provides new tools for modeling bioheating, the thermoelectric effect, and radiation.
The Structural Mechanics Module enables easy access to gravity and Rotordynamic forces, new ways to couple shells with solids, and a new fast penalty method for mechanical contact.
The Acoustics Module supports aeroacoustics simulations using the Linearized Euler equations.
The AC/DC Module comes with a new nonlinear magnetic material library containing 165 materials.
The Wave Optics Module has built-in capabilities for simulating laser heating.
The RF Module allows ports to be assigned to interior boundaries.
The Particle Tracing Module introduces a new efficient method for solving particle-field and fluid-particle interactions with two-way coupling capabilities.
