COMSOL Multiphysics® 5.4 Release Highlights

LiveLink™ for MATLAB® Updates

For users of LiveLink™ for MATLAB®, COMSOL Multiphysics® software version 5.4 brings updated user interfaces for the functions mphnavigator, mphsearch, and mphmodellibrary; improved support for the Join dataset; and a connection for mphlaunch to a graphics server. Browse all LiveLink™ for MATLAB® updates below.

User Interface Updates

The functions mphnavigator, mphsearch, and mphmodellibrary have been updated with new information and features. Using mphnavigator, you can add reports to existing models and generate the reports themselves. Access to help has been improved by giving direct access to the help resources for the COMSOL API.

The menu Tools > Solution opens a table with more information about solutions, datasets, parametric sweeps, and more. This gives a concise overview for advanced models with many studies and advanced solver settings. When selecting Solution nodes (model.sol) or Study nodes (model.study), summary information is shown for the selection node.

Plotting

New plot types are available using mphplot. For example, plots for layered shells and new features for polar plots: start angle, direction, unit, and symmetric angle. The visualization of 3D surfaces is improved in cases where the colors change rapidly over a small portion of the plot. Additionally, the function mphviewselection now has improved graphics for displaying overlapping faces in 2D.

A demonstration of a new plot type for mphplot. Layered slice plot of the second Piola-Kirchhoff stress from the model Thermal Expansion of a Laminated Composite Shell. The COMSOL menu shows the available plots for this model.

More Enhancements

  • It is now possible to extract numerical data from models that use Join datasets
  • mphlaunch is now used to open a COMSOL Multiphysics® session with the same model as the one that is accessible in MATLAB®, making it easier to check settings in models in the COMSOL Desktop® environment while working from the MATLAB® command line
  • Both the mphsolinfo and mphsolutioninfo functions have improved handling of complex models with multiple nested parametric sweeps and/or time-dependent models
