LiveLink™ for MATLAB®


Integrate COMSOL Multiphysics® with MATLAB®Scripting

Seamlessly integrate COMSOL Multiphysics® with MATLAB® to extend your modeling with scripting programming in the MATLAB environment. LiveLink™ for MATLAB® allows you to utilize the full power of MATLAB and its toolboxes in preprocessing, model manipulation, and postprocessing:

  • Enhance your in-house MATLAB code with powerful multiphysics simulations
  • Base your geometry modeling on probabilistic or image data
  • Perform arbitrary statistical analysis on simulation results
  • Use multiphysics models together with Monte Carlo simulations and genetic algorithms
  • Export COMSOL models on state-space matrix format for incorporating into control systems
  • Call MATLAB functions from the COMSOL Desktop®

Product Features

  • Use MATLAB® as a scripting tool to set up and solve your COMSOL models
  • Import/export data from/to the MATLAB®workspace
  • Interface in the COMSOL Desktop® environment enables the use of MATLAB®functions while modeling

Application Areas

  • Preprocess data, such as images and experiments, to include in your models
  • Extract data from your models for customized postprocessing and visualization
  • Manipulate your models from the command line or script to parameterize the geometry, physics, or the solution scheme

  • Define model settings using MATLAB®functions
  • Wrap the solution process in a loop where you can: handle different cases in the solution process; stop and restart a solution based on a specified solution; formulate custom initial conditions

Models

This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the outlet boundary from the previous solution is mapped to the inlet boundary.

Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®.

» See model.

This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval.

The model demonstrates a technique by which you can first stop the time-dependent solver, then restart it with an initial value obtained based on the solution.
