  • Solving PDEs generally means you must take the time to set up the underlying equations, material properties, and boundary conditions for a given problem. COMSOL Multiphysics, however, relieves you of much of this work. The package provides a number of application modes that consist of predefined templates and user interfaces already set up with equations and variables for specific areas of physics. Special properties allow the selection of, for instance, analysis type and model formulations.

  • This chapter contains reference information for all COMSOL Multiphysics commands with descriptions of purpose, syntax, properties, and example scripts. With these commands, you can perform command-line modeling, calling routines for creating geometries, assembling, meshing, solving, postprocessing, and other tasks when using COMSOL Multiphysics with MATLAB.

  • Computer simulation has become an essential par t of science and engineering. Digital analysis of components, in particular, is important when developing new products or optimizing designs. Today a broad spectrum of options for simulation is available; researchers use everything from basic programming languages to various high-level packages implementing advanced methods. Though each of these techniques has its own unique attributes, they all share a common concern: Can you rely on the results?...

  • A coupled-field analysis is a combination of analyses from different engineering disciplines (physics fields) that interact to solve a global engineering problem, hence, we often refer to a coupled-field analysis as a multiphysics analysis. When the input of one field analysis depends on the results from another analysis, the analyses are coupled.

  • Sophisticated miniaturised components and systems may indeed change all kinds of products and equipment in the most dramatic way. Methodology and design of miniaturisation represent a broad research topic with applications in fundamental physics, chemistry, martial science, computing methods, ultra-precision engineering, fabrication technology, micromachining, and many others based on the principles, characterization, modeling, simulation, sophistication, flexibility of state-of-the-art technology.

  • Computational Fluid Dynamics, broadly encompassing fluid flows in engineering, atmospheric and ocean sciences, geophysics, physics and astrophysics, has seen calculations of great fidelity performed routinely that were only imagined at the inception of this conference series in 1989. These advances have not only been made with the available horsepower of increasingly more powerful parallel computers, but in tandem with advances in implementations of core and of entirely new algorithms, including multi-scale and adaptive methods....
