COMSOL® SOFTWARE VERSION 5.5 UPDATE 3

Released February 25, 2020
COMSOL® software version 5.5 update 3 contains performance and stability improvements to COMSOL Multiphysics®, COMSOL Server™, and COMSOL Client. The update applies to COMSOL® software version 5.5 (Build: 292), version 5.5 update 1 (Build: 306) and version 5.5 update 2 (Build: 352). The update can be applied directly to an installation of version 5.5.

If you have a version older than version 5.5 and a valid license that is on subscription, then perform a full installation of version 5.5 from the Product Download page, which will include all updates.

How to Apply the Software Update

Before proceeding with your installation, make sure that you close and exit any running COMSOL® processes or any software you have running that correlates to a LiveLink™ product you would like to update (Excel®, MATLAB®, or a CAD software).

Updating COMSOL Multiphysics®

The easiest way to install the update for COMSOL Multiphysics® is to start the program and then select Check for Product Updates. If using the Windows® operating system, this is located in the File menu under Help. If using the Linux® operating system or macOS, this is located in the Help menu.

For more information on how to install the update and for offline installation, see the Additional Instructions tab below.

In order to check that the update installation was successful, first start the COMSOL Multiphysics® software and select the About COMSOL Multiphysics menu option. If using the Windows® operating system, this is located in the File menu under Help. If using the Linux® operating system or macOS, this is located in the Help menu. The listed version should be COMSOL Multiphysics® 5.5 (Build: 359).

Updating COMSOL Server™

To update COMSOL Server™ if using the Windows® operating system, run the Update program from the COMSOL Launchers folder in the Start menu.

Note that the COMSOL Server™ service process needs to be stopped before applying the update. For more information on how to install the update, installing on other operating systems, and offline installation, see the Additional Instructions tab below.

To check that the installation was successful, first make sure that COMSOL Server™ is running, then navigate to COMSOL Server™ in a web browser and follow the About COMSOL Server™ link in the lower-right corner. The new version should be COMSOL Server™ 5.5 (Build: 359).

Updating COMSOL Client for Use with COMSOL Server™

To update COMSOL Client for the Windows® operating system, download the new version from Client Download and install. The previous 5.5 installation will be overwritten. Your installation of COMSOL Client must have the same version number as the COMSOL Server™ installation that you connect to.

The following instructions apply only if you are not using the method based on the Check for Product Updates menu item, as described above.

COMSOL Multiphysics®

  • For the PID Controller add-in, the coefficients of the proportional and integral terms have changed signs to conform with standard conventions, and it is no longer necessary to specify units for coefficients or terms with the value 0.1
  • The system requirements for the license manager have been expanded to now also support Debian® 6, Red Hat® Enterprise Linux®/CentOS 6, and SUSE® Enterprise Linux® 11.4 and newer.1
  • Fixed a problem with the evaluation of time derivatives of dependent variables from a different frequency domain solution using the withsol operator during assembling.2
  • Improved the refresh action of the Application Libraries window.2
  • Disabled the Run Application button in the Application Libraries window for application previews.2
  • Upgraded the Tomcat server to version 7.0.99.2
  • Reduced window padding for applications running in a web browser.2
  • Pressing the X, Y, or Z key to control rotation in the Graphics window now works on macOS.2
  • The solver sequence now shows the storage format that will be used when running on a cluster.2
  • A problem has been fixed where a running COMSOL® instance could lose contact to the license server if the license file was changed on the license server.2
  • Performance improvements.2
  • A problem has been fixed in the COMSOL Installer that under certain conditions may cause the uninstallation of a LiveLink™ for CAD* product.3
  • Removes a risk for client/server connection problems.3

COMSOL Compiler™

  • For standalone applications compiled with the Download option, the download of COMSOL Runtime™ is more stable.2

Batteries and Fuel Cells Module

  • New electrode material (NMC 811) added to the Batteries & Fuel Cells material library.2

CAD Import Module, Design Module and LiveLink™ Modules for CAD

  • The CAD file import functionality has been extended to support new versions for the following file formats:2

    • Boundaries: Temperature, Heat Flux, Heat Source, and Surface-to-Ambient Radiation

Ray Optics Module

  • Fixed an error in the release of diffraction orders from a grating or cross grating when the reflectance or transmittance of a given order (but not both) is exactly zero.2
  • Fixed an error in the perturbation due to surface roughness for the Illuminated Surface feature in 2D.2
  • Fixed an error when the Include surface roughness check box was selected in some, but not all, of the Illuminated Surface nodes in a geometrical optics model.2
  • Fixed a crash when adding a Height attribute to the Optical Aberration plot, while also applying a filter to the rays.2
  • Adjusted the equation display for the Material Discontinuity node so that the symbols for the transmission and reflection coefficients are more consistent.2
  • For ray release features that display the total number of rays released in a conical distribution, the number shown is now correctly updated after changing the number of azimuthal or polar angles.2
  • Fixed an error in the equation display for the Diffraction Order node in the Geometrical Optics interface.2
  • When releasing rays with one of the conical distributions, Hexapolar or Specify polar and azimuthal distributions, you may now enter zero for the number of polar angles. This will cause a single ray to be released along the cone axis.2

RF Module

  • Fixed a bug resulting in Polar and Smith plot groups becoming empty when rendered in the web client.2

Semiconductor Module

  • Fixed an error in 5.5 update 1 that disallows the selection of the WKB tunneling option in Schottky contacts.2
