COMSOL Multiphysics^® 5.5 Release Highlights

COMSOL Compiler™ Updates

For users of the COMSOL Compiler™ product, version 5.5 of the COMSOL^® software brings smaller executable files and other general improvements. Read more about these COMSOL Compiler™ updates below.

Compile Applications to Smaller Executable Files

Compiled applications use COMSOL Runtime™ in order to run, which needs to be installed on the target computer. You can now create compiled applications that download and install this runtime on-demand, whereas previously it was embedded into each compiled application. By excluding COMSOL Runtime™, you are able to create much smaller executable files for users that already have the runtime installed on their computers. In addition, the runtime itself is now contained in a full-fledged installer, which makes it possible to install and uninstall runtimes for different COMSOL^® software versions.

The COMSOL Runtime™ installer for standalone applications created with the Application Builder in COMSOL Multiphysics^® and compiled with COMSOL Compiler™.

General Improvements

• Support for compiling MPH-files larger than 4 GB on the Windows^® operating system
  • A .dat file is needed to distribute together with the executable
• Improved support for specifying the icon for the compiled executable
  • This includes support for .ico files on the Windows^® operating system and .icns files on macOS
• Custom-made physics interfaces, created with the Physics Builder, are now automatically embedded into the compiled application
  • This makes it much easier to share such applications
• The COMSOL Runtime™ installer now supports installing the necessary components for the bidirectional LiveLink™ for CAD interfaces
  • This makes it much easier to share and run applications that interface CAD software to analyze CAD designs
  • See the System Requirements for Running COMSOL Applications for the list of supported CAD software and operating systems
