Add a Cross Section feature to the Geometry node of the 2D model. Once youвЂ™ve established a suitable Work Plane to intersect with, add a 2D model from the root node, with similar physics and study type as its 3D counterpart. Simplify to Understand and PerfectД¬reating 2D models from 3D geometries is a simple process. Yet, if the simulation had included other physics, such as heat transfer, or required nonlinearities with greater complexity, it would have taken longer to solve. The same model done in 3D produces the same results as the solution presented with the revolved postprocessing of the 2D axisymmetric model. Revolution of the 2D axisymmetric Non-Newtonian Flow model from above using the postprocessing features included in COMSOL Multiphysics. If the simulation included other physics, like heat transfer, or required nonlinearities with greater complexity, it would have taken a bit longer to solve. The simulation was of Non-Newtonian Flow, and it took 3-4 seconds to solve. We hope that you will take advantage of this valuable new functionality as you develop your simulations.ДЄ 2D model was created by taking a 2D work plane from the middle axis to the edge of the 3D geometry, as the original 3D geometry was symmetrical around the axis. You can create 2D cross sections from any 3D model, whether that model was created in 2D originally, created in 3D and imported into COMSOL, or synchronized using the LiveLinkв„ў products. Even with only moderately complex CAD models, this feature can really improve workflow.

This feature is able to simplify the geometry without diminishing its integrity, as seen in the images below. Therefore, we have added a feature for creating 2D models from the cross sections of 3D geometries in COMSOL Multiphysics 4.3b.

This leaves us with two possible solutions: inventing more powerful computers (if we could, we would), or simplifying the models. Should users have to rely on assumptions about the physics they are simulating just to keep projects within a manageable scope? The computers available are simply not fast enough for some extremely complex simulations. This leads to a significant conundrum because changing the model slightly means re-solving, and for computation-heavy models this can be a time-consuming process. Often, your geometries are available as 3D CAD model files and are invariably computation-heavy when simulating a variety of coupled physics. This easy-to-use feature allows engineers to simplify the model, gain understanding of and fine-tune parameters, and dramatically reduce simulation time. One addition to the COMSOL Multiphysics base package we donвЂ™t want you to miss is the ability to create 2D models from cross sections of 3D geometries. Several modules are available for COMSOL, categorized according to the applications areas of Electrical, Mechanical, Fluid, Acoustic, Chemical, Multipurpose, and Interfacing.Our newest release, COMSOL Multiphysics version 4.3b, contains so many new modules and features, certain additions might get lost in the fray.

Users may use drag-and-drop tools (Form Editor) or programming (Method Editor).Д¬OMSOL Server is a distinct software for the management of COMSOL simulation applications in companies. COMSOL provides an IDE and unified workflow for electrical, mechanical, fluid, acoustics, and chemical applications.Д«eside the classical problems that can be addressed with application modules, the core Multiphysics package can be used to solve PDEs in weak form.ДЄn API for Java and LiveLink for MATLAB and Autodesk Inventor may be used to control the software externally.ДЄn Application Builder can be used to develop independent custom domain-specific simulation applications. It allows conventional physics-based user interfaces and coupled systems of partial differential equations (PDEs). COMSOL Multiphysics is a cross-platform finite element analysis, solver and multiphysics simulation software.
