What's New in COMSOL Multiphysics 4.4?
COMSOL Multiphysics is a powerful software platform for modeling and simulating various physical phenomena across multiple disciplines. The latest version, 4.4, was released in November 2013 and brings many enhancements to both user experience and
functionality. In this article, we will highlight some of the new features and improvements that make COMSOL 4.4 a must-have for multiphysics modeling enthusiasts.

New User Interface with Ribbon Design
One of the most noticeable changes in COMSOL 4.4 is the new user interface (UI) with a ribbon design that provides a clearer overview of the modeling workflow and makes it easier to find and access the commands and operations you need. The ribbon only
displays the relevant options for each step of the process, from geometry creation to postprocessing and reporting. The new UI also features a new Multiphysics node that simplifies the setup of multiphysics couplings and physics interfaces.

New Core Functionality and Tools
COMSOL 4.4 also introduces several new features and tools that benefit all users, regardless of the application area. Some of these are:


A new hover-and-click selection method that allows you to select entities by hovering over them and clicking on the desired one.
An auto-complete search tool for variables that helps you find the variables you need by typing a few letters.
User-defined geometric primitives that let you create custom shapes and save them for later use.
If/else statements in the model tree that enable conditional geometry creation based on parameters or expressions.
NASTRAN-mesh file export that allows you to export your mesh to a NASTRAN-compatible format for use in other software.
Time-unit handling in the solvers that automatically converts time units between seconds, minutes, hours, etc.

New Functionality Enhancements Across the Product Suite
In addition to the new UI and core functionality, COMSOL 4.4 also offers many enhancements across the existing products for various application areas. For example:


The CFD Module includes a new boundary condition for modeling wall roughness for turbulent flow and an Outlet boundary condition that improves mass and energy conservation for laminar flow.
The Heat Transfer Module provides new tools for modeling bioheating, thermoelectric effect, and radiation with diffuse-specular reflections.
The Structural Mechanics Module gives 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 introduces the Linearized Euler equations for aeroacoustics simulations.
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 implements a new efficient method for solving particle-field and fluid-particle interactions with two-way coupling capabilities.

Conclusion
COMSOL Multiphysics 4.4 is a major update that brings a fresh look and feel, as well as state-of-the-art enhancements to both user experience and functionality. Whether you are a new or experienced user, you will find COMSOL 4.4 to be an invaluable tool
for creating even the most advanced multiphysics models. To learn more about COMSOL 4.4, visit https://www.comsol.com/release/4.4
