If you are using COMSOL 3.2 software products, it is recommended that you upgrade to COMSOL 3.2a. See Installation below for information on how to check your COMSOL software version and how to install the COMSOL 3.2a update.
Release Notes
You find information about new features and updates to the documentation in the COMSOL 3.2a Release Notes.
Installation
Before you begin, make sure that you run COMSOL version 3.2.0.222 or 3.2.0.224. These are the only versions that can be updated with the 3.2a software update. On the Help menu, click "About COMSOL Multiphysics" to check your version.
32-bit PC Installation Instructions
Download the self-extracting executable file c32a_win32.exe. Close all instances of COMSOL Multiphysics 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.ini and the directories comsol and doc are located.
Note: Applying the update clears the settings in the comsol.opts file in the bin directory of the installation. This
means that if you are using COMSOL with MATLAB, you may need to change the path to your MATLAB installation. Edit line 9 in comsol.opts
to reflect the directory of your MATLAB installation.
64-bit PC Installation Instructions
Before installing the 64-bit version, make sure your system fulfills the 64-bit system requirements:
- Windows XP Professional x64 Edition
- A PC with one of these processors: AMD Opteron, AMD Athlon 64, Pentium 4 with EM64T, or Xeon with EM64T
- A graphics card with at least 32 MB of memory
- At least 256 MB of system memory
The 64-bit version also contains the 32-bit binaries related to the 3.2a upgrade so you do not need to download both the 32- and 64-bit version.
Download the self-extracting executable file c32a_win64.exe. Close all instances of COMSOL Multiphysics 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.ini and the directories comsol and doc are located.
Right-click the "COMSOL Multiphysics" icon on the Desktop and select "Properties". In "COMSOL Multiphysics 3.2 Properties", on the "Shortcut" page, change "Target:" from C:\COMSOL32\bin\comsol.exe to C:\COMSOL32\bin\comsol64.exe. If you selected another installation directory than C:\COMSOL32, the path to the executable might be different than above. Click OK. Right-click on the newly created shortcut and rename it "COMSOL Multiphysics 3.2a (64-bit)". (The 32-bit version of COMSOL Multiphysics has also been upgraded to version 3.2a, so you could rename its shortcut too to reflect this.)
Note: Applying the update clears the settings in the comsol.opts file in the bin directory of the installation. This
means that if you are using COMSOL with MATLAB, you may need to change the path to your MATLAB installation. Edit line 9 in comsol.opts
to reflect the directory of your MATLAB installation.
UNIX and Linux Installation Instructions
You have the option of downloading one of the following files
| c32a_glnx86.tar.gz | Linux, gzipped version |
| c32a_glnxi64.tar.gz | Linux with Itanium 2 support, gzipped version |
| c32a_glnxa64.tar.gz | Linux with AMD64/EM64T support, gzipped version |
| c32a_hpux.tar | HP-UX, uncompressed version |
| c32a_hpux.tar.gz | HP-UX, gzipped version |
| c32a_solaris.tar | Solaris, uncompressed version |
| c32a_solaris.tar.gz | Solaris, gzipped version |
On HP-UX and Solaris, please download the gzipped version if you have
the gzip tools available. Uncompress the file by typing, for example,
gunzip c32a_hpux.tar.gz
Unpack the tar archives in the COMSOL installation directory, for
example, /usr/local/comsol32 by typing
cd /usr/local/comsol32
tar xf {download directory}/c32a_hpux.tar
on HPUX, and
cd /usr/local/comsol32
tar xf {download directory}/c32a_solaris.tar
on Solaris. On Linux, and if you have the GNU tar command available
on HP-UX or Solaris, you can type
cd /usr/local/comsol32
tar xzf {download directory}/c32a_glnx86.tar.gz
Note: Applying the update clears the settings in the comsol file in the bin directory of the installation. This
means that if you are using COMSOL with MATLAB, you may need to change the path to your MATLAB installation. Edit line 3 in comsol
to reflect the directory of your MATLAB installation.
Mac OS X Installation Instructions
Download the file c32a_macosx.dmg. Mount the downloaded disk image by double-clicking it. Run the AppleScript "COMSOL 3.2a Installer". It will ask you to locate your COMSOL installation folder, for example, "Macintosh HD:Applications:COMSOL32". This is the folder where the file comsol.ini and the folders comsol and doc are located.
Note: Applying the update clears the settings in the comsol file in the bin directory of the installation. This
means that if you are using COMSOL with MATLAB, you may need to change the path to your MATLAB installation. Edit line 3 in comsol
to reflect the directory of your MATLAB installation.
Check the Installation
Do the following to check that the installation is complete:
- Start COMSOL Multiphysics
- Click OK in the Model Navigator
- On the Help menu, click About COMSOL Multiphysics.
- Check that the version number is 3.2.0.300 (If the installation did not finish correctly, the version number is 3.2.0.222 or 3.2.0.224).
