Install

Before you proceed with the installation, make sure to exit any running COMSOL process.

Windows

Run the downloaded .exe-file to extract the update to the COMSOL 4.3 installation directory, for example C:\Program Files\COMSOL\COMSOL43.

Linux

Copy the downloaded .zip-file to the COMSOL 4.3 installation directory:

cp comsol_4.3.0.184_linux.zip [installdir]/comsol43

where [installdir] is the root of the installation, for example /usr/local. Unzip it by the commands:

cd [installdir]/comsol43
unzip -o comsol_4.3.0.184_linux.zip

If you have not disabled SELinux, run the following command:

chcon -t textrel_shlib_t [installdir]/comsol43/lib/[platform]/lib*

where platform is glnx86 or glnxa64.

Macintosh

Double-click the downloaded .dmg file to mount the disk image. In the Finder, open the mounted disk and double-click the COMSOL installer icon. Select your COMSOL installation folder, usually called COMSOL43.

Check your installation

  1. Start COMSOL Multiphysics.
  2. On the Help menu, click About COMSOL Multiphysics.
  3. Check that the version number is 4.3.0.184 (If not, the installation did not succeed).
