Equation-Based Modeling in COMSOL Multiphysics
Model 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.
