  2. What is COMSOL Multiphysics?

  3. COMSOL • COMSOL Multiphysics is a finite element analysis, solver and simulation software / FEA software package for various physics and engineering applications, especially coupled phenomena, or multiphysics. • COMSOL Multiphysics also offers an extensive interface to MATLAB and its toolboxes for a large variety of programming, preprocessing and postprocessingpossibilities. • The packages are cross-platform (Windows, Mac, Linux). • In addition to conventional physics-based user interfaces, COMSOL Multiphysics also allows for entering coupled systems of partial differential equations (PDEs). • The physics-based modules augment the core physics interfaces of COMSOL Multiphysics and provide additional physics interfaces for electrical, mechanical, fluid flow, and chemical applications.

  5. Expiry date of COMSOL Multiphysics August 31th, 2014

  6. Renewal of COMSOL Multiphysics • Every a year, renewal of COMSOL Multiphysics is necessary. Normally, renewal price is 20% of first purchasing. • Firstly, please get the quotation from ALTSOFT designated by COMSOL Inc.. If you want to contact this company and phone number, please click following link. (http://www.altsoft.co.kr) • Sometimes, specific module can be purchased inexpensively. That’s why when you request new quotation, asking price of each modulesevery a year in detail. • Technical Support: Applying technical support during a year from renewal date • Warranty: Applying complimentary update of new version during a year from renewal date • Warning : When receiving upgrade and renewing after expiry date, additionally period retroactivity and restart fee (15% of first purchasing) will be charged. • After completing subscription period, subscription renewal should be preceded for license change or reissue.

  7. COMSOL Multiphysics • User Interfaces for Modeling and Simulation • Physics and Equation-Based Modeling Interfaces • Using COMSOL Multiphysics provides you with a significant amount of physics modeling functionality, including multiphysics ability. By adding application-specific modules, the modeling power is increased with dedicated tools for electrical, mechanical, fluid flow, and chemical applications. • Coordinate Systems • Users enjoy the ability to define any number of local coordinate systems. There are shortcuts for common coordinate systems such as cylindrical, spherical, and Euler-angle based, and a method for automatic coordinate system creation makes it easy to define anisotropic material properties that follow curved geometric shapes. • Model Couplings • The COMSOL Desktop® allows you to work simultaneously in 3D, 2D, 1D, and 0D. So called Model Couplings can be used to map any quantity across spatial dimensions.

  8. COMSOL Multiphysics cont. • Meshing Types • Automatic and semi-automatic meshing tools are available in COMSOL Multiphysics, including free tetrahedral meshing and swept meshing. • The default algorithm is automatic tetrahedral meshing for physics defined in solids, and a combination of tetrahedral and boundary-layer meshing for fluids. • You can also take full control over the sequence of operations used for creating the mesh by defining a so-called mesh sequence.

  9. COMSOL Multiphysics cont. • Finite Element Types • COMSOL's unique approach to multiphysics separates the geometric shape of the finite elements from the "finite element shape functions". • This provides maximum flexibility, and each geometric shape supports first, second, third, and, in some cases, higher-order shape functions, corresponding to traditional linear, quadratic, or cubic finite elements respectively. • Many types of physics utilize Lagrange finite elements, also know as isoparametric nodal-based finite elements. This includes heat transfer, structural mechanics, electrostatics, and more. • For CFD, specialized elements and numerical stabilization schemes are also used. • For vector-field electromagnetics, curved and higher-order curl elements, also known as edge or vector elements, are used.

  10. COMSOL Multiphysics cont. • Geometry Modeling • COMSOL Multiphysics provides 1D, 2D, and 3D geometry modeling tools with a COMSOL native geometry kernel. • A number of primitive objects are available, as well as the capability of extruding general 2D geometry objects into 3D. • Additionally, 2D objects can be revolved or swept along parametric curves.

  11. COMSOL Multiphysics cont. • State-of-the-Art Numerical Methods • COMSOL Multiphysics assembles and solves models using state-of-the-art numerical analysis methods. • Several different methods are used in the add-on modules, including finite element analysis, the finite volume method, the boundary element method, and particle tracing methods, but the emphasis of COMSOL Multiphysics is on the finite element method. • Parametric and Associative Models • COMSOL creates sequences to record all steps that create the geometry, mesh, studies and solver settings, visualization, and results presentation. • You can therefore easily parameterize any part of the model, by simply changing a node in the Model Tree and re-running the sequences.

  12. COMSOL Multiphysics cont. • Variables, Expressions, and Look-up Tables • COMSOL Multiphysics comes with a built-in interpreter for mathematical expressions. • Expressions can be assigned to variables for later use in material properties, boundary conditions, or sources. • This means that most of the time you do not need to write code to adapt the software when there is a need for a custom expression. • APIs and the Physics Builder • Although the COMSOL Desktop® environment lends itself for easy and general customization, a number of different application programming interfaces (APIs) are available. • The Physics Builder, which is included in COMSOL Multiphysics, allows you to create your own physics interfaces accessible from the COMSOL Desktop® with the same look-and-feel as the built-in physics interfaces.

  13. COMSOL Multiphysics cont. • Exporting Results and Generating Reports • Results can be exported to text files on the .txt, .dat,and .csvformats, the Microsoft® Excel®on the .xlsx format, images on several common image formats and animations on Animated GIF, Adobe® Flash, or AVI. • Reports summarizing the entire simulation project can be exported to HTML (.htm,.html) or Microsoft® Word® (.doc) format.

  14. COMSOL Multiphysics cont. • Results Visualization and Postprocessing • Visualization capabilities include surface, slice, isosurface, cut plane, arrow, and streamline plots, as well as many other plot types. • A range of postprocessing tools are available for evaluation and integration. • You can compute the max, min, average, and integrated values of any quantity or composite quantities, throughout volumes, on surfaces, along curved edges, and at points.

  15. COMSOL Multiphysics cont. • Verify and Optimize your Simulations • COMSOL Multiphysics is a flexible platform that allows users to model all relevant physical aspects of their designs. • Expert users can dig deeper and use their knowledge to develop customized solutions, applicable to their unique circumstances. • With this kind of all-inclusive modeling environment, COMSOL gives you the confidence to build the model you want with real-world precision.
