Equation-Based Modeling in COMSOL Multiphysics
Application ID: 14863
Partial differential equations (PDEs) constitute the mathematical foundation for describing the laws of nature. This presentation provides an introduction to customizing your simulations by developing models directly with PDEs. Learn how to add ordinary differential equations (ODEs) and algebraic equations to your model. Equation-based modeling is a powerful method eliminating the need for user-written subroutines. Once a system of equations has been defined, you can combine them with any other physics-based user interface in the COMSOL environment. Typical applications for equation-based modeling are: custom materials definitions, phase change, and time-dependent loads and sources.
This model example illustrates applications of this type that would nominally be built using the following products:CAD Import Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
