Compatibility tests of COMSOL 3.2a/3.2b and MATLAB R2006a have been done. The tests indicate that COMSOL 3.2a/3.2b is compatible with MATLAB R2006a on all platforms except Linux. See the Knowledge Base solution 987 Running COMSOL 3.2a and COMSOL 3.2b with MATLAB R2006a on Windows, Solaris, and Macintosh for instructions on how to run COMSOL 3.2a/3.2b with MATLAB R2006a on other platforms than Linux. To run on Linux you need to install the hotfix as described below.

Note: The update is not compatible with use of the CAD Import Module. The update also makes your COMSOL 3.2a/3.2b installation incompatible with earlier versions of MATLAB. We expect that these issues will be resolved in the next major release of COMSOL, scheduled for early fall 2006. In case you need compatibility with the CAD Import Module and/or earlier versions MATLAB, we suggest that you make two COMSOL installations: One for use with the CAD Import Module and/or earlier versions of MATLAB and one for use with MATLAB 7.2.

Make sure you apply this update to COMSOL 3.2a/3.2b. Check that your version number is 3.2.0.300, 3.2.0.301, or 3.2.0.304 by opening the About dialog box in COMSOL Multiphysics.

For 32-bit Linux, apply the 32-bit hotfix and for 64-bit Linux, apply both the 32-bit hotfix and 64-bit hotfix.

Go to the COMSOL installation directory, for example:
cd /usr/local/comsol32a

Then apply the update(s)
tar xzf <download dir>/comsol32a-ml72-glnx86.tar.gz (32-bit version)
tar xzf <download dir>/comsol32a-ml72-glnxa64.tar.gz (64-bit version)

Make sure the variable MLROOT in the script bin/comsol is set to the MATLAB R2006a installation directory, for example:
MLROOT=/usr/local/matlab/R2006a
