System Requirements - 5.1 COMSOL Multiphysics

These requirements are common to all platforms

  • A working network card and internet connection is recommended during installation.
  • At least 1 GB memory, but 4 GB per processor core or more is recommended.
  • 1-5 GB of disk space, depending on your licensed products and installation options.
  • Adobe® Acrobat® Reader 9.0 or later to view and print the COMSOL® documentation in PDF format.

Floating Network Licenses

The floating network license type is supported on heterogeneous networks of Windows®, Linux®, and Mac OS X computers. Both the license manager and the COMSOL® software can run on either Windows®, Linux®, or Mac OS X, and a single computer can run both of them. This license type is recommended for best high-performance computing (HPC) performance and is required for distributed-memory parallelism including hybrid modeling.

Class Kit License (CKL)

System requirements for the class kit license type are similar to that of the floating network license type.

Application Builder

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

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, the Design Module, and the LiveLink product suite.

OS Specific System Requirements


GNU C Library version 2.8 or later1
Linux® kernel 2.6.18 or later
Intel® Pentium® IV or AMD Athlon® XP processor or later
Flexnet® requires Linux Standard Base (LSB).

1 If you have an older version of libstdc++ than 6.0.9 you may need to start comsol with the option -forcegcc

Help system on Linux

In order for the help system to work on Linux, the following packages need to be installed:

  • Debian and Ubuntu: libwebkitgtk-1.0-0
  • RHEL: webkitgtk (not included in RHEL7 but available through EPEL).
  • openSuSE: libwebkitgtk-1.0-0 or libwebkit-1_0-2 depending on version.

If these requirements are not met, COMSOL crashes when accessing the help system.

Graphics System Requirements

COMSOL® recommends hardware rendering for performance reasons. Hardware rendering requires drivers that support OpenGL® version 1.4. Windows® 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® 2.0. Software rendering also supports 16-bit color graphics. For performance reasons, we recommend that the graphics card has at least 512 MB memory.

The graphics cards listed above have been rigorously tested for compatibility with COMSOL Multiphysics®. 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 you graphics card vendor, such as NVIDIA or AMD, otherwise use COMSOL® software rendering. The Nouveau video driver is only supported for software rendering.

All computers in the cluster must use the same Linux® version and should have similar hardware. It is recommended that OpenFabrics Enterprise Distribution (OFED) 1.4 or higher is installed. If you are using an RDMA-capable network fabrics a DAPL 1.2 or later version compliant driver or library is required. The software is usually provided with your hardware.

* COMSOL is a proud member of the Intel® Cluster Ready program and certifies COMSOL Multiphysics with every new version. View Certificate. The certification process ensures that COMSOL Multiphysics will seamlessly work for parallel processing and cluster modeling on any hardware that has also been certified as being Intel Cluster Ready.

FLEXnet License Manager

The system requirements for the license manager are the same as for COMSOL Multiphysics. FLEXnet version 11.12 is used on all platforms. The version of lmgrd must be the same or higher than the FLEXnet version used by COMSOL.

FlexNet License Manager on Linux

Linux Standard Base (LSB) is now required for Linux on the license server computer.
