This fix addresses the following:

• Physics settings in 3.1 models are lost when changing geometry in draw mode.
• Not possible to open transient piezo models created with 3.1.
• Not possible to open models with a ' character as constant description.
• Issues related to named groups and predefined materials.
• 3D plots not supported in custom GUIs created in COMSOL Script™.
• Legend command does not refresh figure window correctly.
• Problem removing text objects using the plot edit dialog box.
• COMSOL batch requires a valid graphics display even when graphics is not used.
• The fzero function has been added to COMSOL Script.

Before you begin, make sure that you run COMSOL version 3.2.0.222. This is the only version that can be updated with this fix. On the Help menu, click "About COMSOL Multiphysics" to check your version.

PC Installation Instructions

Download the self-extracting executable file comsol32_p1.exe. Close all instances of COMSOL Multiphysics, COMSOL Script, and MATLAB before you begin the installation process. Run the executable and unpack the files to your COMSOL installation directory, for example, C:\COMSOL32. This is the directory where the file licenseinfo.txt and the directories multiphysics and doc are located.

UNIX and Linux Installation Instructions

Download the tar file comsol32_p1.tar. Connect to the COMSOL installation directory, for example, /usr/local/comsol (type cd /usr/local/comsol32). Type

tar xf [download file path]/comsol32_p1.tar

to apply the hotfix.

Mac OS X Installation Instructions

Mount the downloaded disk image by double-clicking it. Run the AppleScript "COMSOL 3.2 Installer". It will ask you to locate your COMSOL installation folder, for example, "Macintosh HD:Applications:COMSOL32". This is the folder where the file licenseinfo.txt and the directories multiphysics and doc are located.

Do the following to check that the installation is complete:

1. Start COMSOL Multiphysics.
2. On the Help menu, click About COMSOL Multiphysics.
3. Check that the version number is 3.2.0.224 (If the installation did not finish correctly, the version number is 3.2.0.222).
