A particular strength is its ability to account for multiphysics phenomena. The physics interfaces are dedicated user interfaces for a particular scientific or engineering field, where all aspects for modeling the phenomena in question are made available for manipulation — from defining the model parameters to discretization to analyzing the results of the solution. In converse to defeaturing, virtual operations do not change the curvature or fidelity of the geometry, while yielding a cleaner mesh. View a list of studies. The Application Builder allows simulation experts to create intuitive and very specific user interfaces for their otherwise general computer models — ready-to-use custom applications. Geometries are defined by sequences of operations, where each operation is able to receive input parameters for easy edits and parametric studies in multiphysics models.

Geometries are defined by sequences of operations, where each operation is able to receive input parameters for easy edits and parametric studies in multiphysics models. By using this site, you agree to the Terms of Use and Privacy Multiohysics. The direct solvers can be used for small- and midrange-sized problems, while the iterative solvers can be used for larger linear systems.

The general model can serve as a starting point for several different applications, each with its own restricted input and output options relevant for a multpihysics task. Often, the key to successful engineering simulations is developing experimentally validated models that replace the use of experiments and prototypes alone, and give a deeper understanding of the studied design or process. Comsol is releasing version 3.

The predominant discretization methods are finite-element based for a complete list of methods, see the solvers section of this page. The geometry fomsol a model depicting part of a circuit board with a chip mounted via solder ball joints has been meshed using a manual mesh sequence combining tetrahedral, triangular, and swept meshes.

It introduces Multiphysicw Script, a standalone product featuring command-line modelling. To make it easy for users to import Cad fsmlab for modelling in Comsol Multiphysics, a suite of optional Cad-import modules read a wide range of industry-standard Cad and mesh file formats starting with those for SolidWorks, Solid Edge, NX, and Nastran.

Union, intersection, difference, and partition Transformations: A range of numerical postprocessing tools are available for evaluation of expressions, such as multiphysivs and derivatives. Users may use drag-and-drop tools Form Editor or programming Method Editor. Study step sequences structure the solution process to allow you to select the model variables for which you want to solve in each study step. For space- and time-dependent problems, the method of lines is used, where space is discretized with FEM or BEMthus forming a system of ordinary differential equations ODEs.

Intense research has made Comsol Multiphysics the only finite-element based software that performs time-domain simulation of electromagnetic waves, the company claims. Geometric entities such as material domains and surfaces can be vomsol into selections for subsequent use in physics definitions, meshing, and plotting.

By talking to one of our sales representatives, you will get personalized recommendations and fully documented examples to help you get the most out of your evaluation and guide you to choose the best license option to suit your needs. A damped Newton method is used for solving the nonlinear system for stationary problems or during time stepping for time-dependent problems.

New solvers address far larger problems and at faster speeds. By working with such scripts, users can conduct iterative parametric studies multiphyscis optimisations as well as perform any model explorations and simulations. Please help multiphydics it by removing promotional content and inappropriate external linksand by adding encyclopedic content written from a neutral point of view. Coupled with the moving-mesh engine is geometric parameterisation, where it is possible to describe how a geometry changes without the need to set up a loop in a script file.

You can also be creative in a way that is impossible or comwol lot harder with traditional approaches, thanks to the ability to couple any number of physics phenomena together and input user-defined physics descriptions, with associated equations and expressions, directly in the graphical user interface GUI.

For example, for solid mechanics analyses, the software suggests time-dependent, stationary, or eigenfrequency studies; for CFD problems, the software would only suggest time-dependent and stationary studies. On its own, this interpreted language handles most computation tasks through its command-line interface, scripting mu,tiphysics, and commands for numeric computations and visualisation.

The graphical user interface encourages the use of a consistent system of engineering units, and a moving-mesh feature allows a model to multiphyzics moving parts and parametric geometries.

In many organizations, a small group of numerical simulation experts is servicing a much larger group of people working in product development, production, or as students studying physics phenomena and processes. FEM Nodal-based Lagrange elements and serendipity elements of different orders Curl elements also called vector or edge elements Petrov-Galerkin and Galerkin least square methods for convection-dominated problems and fluid flow Adaptive mesh and automatic mesh refinement during the solution process BEM Discontinuous Galerkin method Space-time discretization: The connection between the geometry definition and defined physics settings is comxol associative — a change in the geometry will automatically propagate related changes throughout the associated model settings.
