![]() Once you have downloaded the software, you can install it on your computer and start exploring the new features and enhancements. If you do not have a COMSOL Access account yet, you can create one for free. Trial licenses are automatically associated with your account. You will need an on-subscription COMSOL license attached to your COMSOL Access account or a software trial provided by your sales representative. If you are interested in trying out COMSOL Multiphysics 4.4, you can download it from the. Some examples of multiphysics simulations using COMSOL Multiphysics 4.4 products. The Particle Tracing Module introduces a new efficient method for solving particle-field and fluid-particle interactions with two-way coupling capabilities. The RF Module allows ports to be assigned to interior boundaries. The Wave Optics Module has built-in capabilities for simulating laser heating. ![]() The AC/DC Module comes with a new nonlinear magnetic material library containing 165 materials. The Acoustics Module supports aeroacoustics simulations using the Linearized Euler equations. 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 Heat Transfer Module provides new tools for modeling bioheating, the thermoelectric effect, and radiation. 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. In addition to the new UI, COMSOL Multiphysics 4.4 also offers many functionality enhancements across the existing products. The new UI of COMSOL Multiphysics 4.4 with ribbon design and Multiphysics node.įunctionality Enhancements Across the Product Suite 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. ![]() You can also customize the couplings by adding or removing terms, changing signs, or modifying coefficients. For example, you can easily define thermal stress and electromagnetic thermal effects using the Multiphysics node. ![]() The new Multiphysics node gives you more control over the couplings between different physics phenomena in your models. The ribbon only displays the relevant commands for each step of the modeling process, such as geometry, physics, mesh, study, and results. 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. 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.
