System Requirements: COMSOL Multiphysics^® Version 5.5

These requirements are common to all platforms:

• A working network card and internet connection are recommended during installation
• At least 4 GB of RAM is recommended
• 2–10 GB of disk space, depending on your licensed products and installation options
• Adobe^® Acrobat^® Reader to view and print the COMSOL documentation in PDF format
• An Intel^® or AMD^® 64-bit processor based on the Intel^® 64 or AMD64 architecture¹

For further recommendations concerning hardware, please see our Knowledge Base entry.

¹_{A processor with the SSE4 instruction set is required for the Design Module on Linux^®. Intel^® processors released 2009 or later and AMD^® processors released 2012 or later satisfy this requirement.}

Operating System Requirements

In addition to the operating system requirements listed below, see the Interfacing Product Suite Requirements for specific requirements for the CAD Import Module, Design Module, and the LiveLink™ products. The system requirements for COMSOL Compiler™, and compiled applications, are identical to those for COMSOL Multiphysics^®.

OS-Specific System Requirements

¹See FlexNet^® License Manager on Linux^® below.

Help System on Linux^®

In order for the help system to work on Linux^® operating system, any of the following packages need to be installed (depending on Linux^® distribution and version):

• libwebkitgtk-1.0-0
• libwebkitgtk-1_0-0
• webkitgtk
• webkitgtk4
• libwebkit2gtk-4_0-37

FlexNet^® License Manager

The system requirements for the license manager are the same as for COMSOL Multiphysics^®. In addition to the Linux^® system requirements, the license manager supports Red Hat^® Enterprise Linux^®  6, SUSE^® Linux Enterprise Desktop® 11.4, and Debian^® 6 and later. FlexNet^® version 11.16.2.1 is used on all platforms. The version of lmgrd must be the same or higher than the FlexNet^® version used by the COMSOL^® software.

Note: the COMSOL^® license server was upgraded from FlexNet^® version 11.15.1 in COMSOL^® 5.4 to 11.16.2.1 in COMSOL^® 5.5. This means that the COMSOL^® license server needs to be upgraded to COMSOL^® 5.5 to allow installation of COMSOL^® 5.5.

FlexNet^® License Manager on Linux^®

Linux Standard Base (LSB™) is required for Linux^® on the license server computer.

If the LSB™ core package is missing from the distribution repository, manually create a symbolic link as root:

ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3

Application Builder

The Application Builder is supported in the Windows^® operating system.

Add-In for Microsoft^® PowerPoint^®

The COMSOL add-in for PowerPoint^® is compatible with PowerPoint^® 2010, 2013, 2016, and 2019 on the Windows^® operating system. PowerPoint^® 2010 Starter is not supported. If you are using Office 365, PowerPoint^® must be installed on the computer — the add-in requires a version of PowerPoint^® that supports VSTO add-ins.

Parallel System Requirements

COMSOL Multiphysics^® version 5.5 has been validated on systems compatible with the Intel HPC Platform Specification and thus will be compatible with Intel^® Select Solutions for Simulation and Modeling.

For information on how you can run COMSOL Multiphysics^® and COMSOL Server™ in the cloud, please view this page.

Officially Supported Compilers

COMSOL Multiphysics^® provides external C interfaces for external functions, external materials, and external C libraries in the Application Builder.

COMSOL Multiphysics^® is built and tested with the above C/C++ compilers. Please note that later versions of those C/C++ compilers may also be compatible with the external C interfaces. When using the COMSOL API for use with Java^® API in client/server mode with the jar files listed in <installation dir>/bin/comsolclientpath.txt, JRE 1.7 and JRE 1.8 are supported. When using the COMSOL API for use with Java^® API in standalone mode with the jar files listed in <installation dir>/bin/comsolpath.txt, JRE 1.8 is supported.

Graphics System Requirements

COMSOL recommends hardware rendering for performance reasons. Hardware rendering requires drivers that support OpenGL^® version 2.0. Windows^® operating system users may also use DirectX^® version 9 on the local console. Hardware rendering requires at least 24-bit color graphics.

The Optimize for Quality setting in the Graphics preferences requires OpenGL^® 2.1. Software rendering also supports 16-bit color graphics. For performance reasons, we recommend that the graphics card has at least 512 MB memory.

AMD^®

Windows^® 10

Windows^® 8.1

Linux^®-based operating systems

NVIDIA^®

Windows^® 10

The graphics cards listed above have been rigorously tested for compatibility with the COMSOL Multiphysics^® software. Please note, however, that other AMD^® or NVIDIA^® graphics cards may also be compatible with COMSOL Multiphysics^®. Graphics cards that belong to the same model series as one of the cards listed above are more likely to be compatible with COMSOL Multiphysics^®.

For hardware acceleration on Linux^®, use proprietary drivers from your graphics card vendor, such as NVIDIA^®; otherwise, use COMSOL^® software rendering. The Nouveau video driver is only supported for software rendering.

Note: This information is provided for your benefit but should not be used as a substitute for your own investigation of the system requirements that may be appropriate for your use of COMSOL^® software or other software, given your particular circumstances. Systems and hardware change regularly, which may impact any determination of what system requirements are appropriate for you.
