System Requirements

General Requirements

These requirements are common to all platforms:

The actual disk space needed varies with the size of the partition and the optional installation of online help files. The COMSOL installer informs you of hard-disk space requirements for a particular installation.

General System Recommendations

We recommend at least 1 GB of memory. The solutions of a few examples in the Model Library require substantially more than 1 GB of memory and some even a 64-bit platform.

Floating Network Licenses

Floating network licenses are supported on heterogeneous networks of Windows, Linux, Sun, and Mac computers. Both the license manager and the COMSOL application can run on either Windows, Linux, Sun, or Mac, and a single computer can run both of them.

COMSOL Multiphysics System Requirements for Microsoft Windows

System Requirements - 32-bit Windows Version

System Requirements - 64-bit Windows Version

Windows System Recommendations

We recommend that you use Automatic Updates to keep your Windows system up-to-date. You can access it and turn it on from the Control Panel.

COMSOL Multiphysics System Requirements for Linux and Sun

System Requirements

Standalone COMSOL Multiphysics, the COMSOL Multiphysics client, and the COMSOL Multiphysics server are available in 32- and 64-bit versions as indicated in the table:

Platform Operating System Processor
32-bit Linux Linux 2.4.x kernel, glibc-2.2.5 or later Pentium III or later
64-bit Linux Linux 2.4.x kernel, glibc-2.3.2 or later AMD with AMD64 or Intel with EM64T
Itanium Linux 2.4.x kernel, glibc-2.3.2 or later Itanium 2
Sun Solaris 8, 9, 10 UltraSPARC II or later

Note: On the Itanium 2 only the 64-bit COMSOL Multiphysics server is available. Here you must run the COMSOL Multiphysics client on a COMSOL Multiphysics platform other than Itanium using a floating network license to access the COMSOL Multiphysics server.


The following Linux distributions are officially supported by COMSOL.

Platform Distribution
32-bit Linux Debian 3.0, 3.1, RedHat Enterprise 4, Fedora Core 5, SUSE 10.1
64-bit Linux SUSE 9.0, 9.3, and 10.1, RedHat Enterprise 4 (AMD64/Intel EM64T), Fedora Core 5
Itanium Debian 3.1 (IA-64), RedHat Enterprise 4 (Itanium)

In addition, see the graphics requirements in the following sections.

Linux Graphics Requirements

You can use any of the following XFree86 and graphics driver configurations:

Sun Graphics Requirements

Frame Buffer with OpenGL support (XVR-500, XVR-1000, XVR1200, XVR-4000, Expert3D, Elite3D, Creator3D, or PGX).

OpenGL 1.2.2 for Solaris or later. Depending on the type of frame buffer, a higher OpenGL version might be needed; for instance, XVR-1000 requires OpenGL 1.2.3.

COMSOL Multiphysics System Requirements for Mac

System Requirements - Intel Processor

System Requirements - PowerPC Processor

System Requirements for COMSOL Desktop - PowerPC Processor

Optional MATLAB Add-On Requirements

The following chart indicates available MATLAB interfaces in COMSOL 3.4.

¹ The CAD Import Module is not compatible with use of the interface to MATLAB 2007a/b on Sun.

CAD Import Modules Platform Support

Find the platform support for products in the CAD Import Module family in the following table:

Product Required Products Platform Support
CAD Import Module COMSOL Multiphysics Windows, Linux¹, Sun²
CATIA V4 Import Module CAD Import Module Windows, Linux¹, Sun²
CATIA V5 Import Module CAD Import Module Windows
Inventor Import Module CAD Import Module Windows
Pro/E Import Module CAD Import Module Windows, Linux¹, Sun²
VDA-FS Import Module CAD Import Module Windows, Linux¹, Sun²

¹ Only 32-bit Linux and 64-bit Linux are supported. The Itanium platform is not supported.
² On Sun, the CAD Import Module is not compatible with use of the interface to MATLAB 2007a/b (64 bit only).

The SolidWorks Live Connection has been tested with SolidWorks 2005 SP5.0, SolidWorks 2006 SP0 and SP5.1, SolidWorks 2007 SP0 and SP4.0, and SolidWorks 2008 SP0. It is available on Windows 2000, Windows XP, Windows XP x64, Windows Vista Business and Ultimate (32 bit only). Supported on the Windows XP x64 platform are connections between SolidWorks 64 bit and COMSOL Multiphysics 64 bit, as well as between SolidWorks 32 bit and COMSOL Multiphysics 32 bit.

COMSOL Script System Requirements

The system requirements of COMSOL Script are similar to those for COMSOL Multiphysics except that COMSOL Script is not available on the Itanium platform.
