Flow Science supports FLOW-3D on 64-bit Windows and Linux platforms. The configurations below have been updated for FLOW-3D v11.2.
Supported Operating Systems
- x86-64 (Intel/AMD)
- 64-bit Windows 7, Windows 8, Windows 8.1, Windows 10, Windows Server 2008, and Windows Server 2012
- 64-bit Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7 and 64-bit SUSE Enterprise Linux 12
Support for users who have installed FLOW-3D on “compatible” Linux distributions (such as Fedora, Scientific Linux, Debian, Ubuntu) will only be provided when a problem can be reproduced on Flow Science’s RedHat and Novell enterprise-class Linux distributions.
For those interested in running the distributed-memory version of FLOW-3D, you can find more information about hardware and operating systems on the FLOW-3D/MP Supported Platforms page.
FLOW-3D and FlowSight require modern graphics cards with up-to-date drivers to perform satisfactorily. nVidia Quadro K and M series cards are highly recommended. nVidia driver version 341.05 or newer is highly recommended.
AMD FirePro W series cards and nVidia GT/GTX graphics cards work with some limitations, including difficulty with remote visualization tools such as Remote Desktop.
Intel integrated graphics cards are not supported. Built-in server motherboard graphics cards do not support 3d acceleration and are not supported
License Server Software
FLOW-3D uses FLEXlm for license management. If you choose to employ the FLEXlm floating manager on a Windows network, your network server must be running Microsoft Windows 7, 8, 8.1, 10, Server 2008, or Server 2012 and you must use a hardware key (dongle).
Memory and Processor Speed
A minimum of 2GB of RAM is recommended per processor core. For example, a workstation with two 6-core CPUs should have at least 24 gigabytes of memory. Note however that the amount of RAM required is highly problem dependent. For simulations with large domains, or with complex geometry requiring fine resolution, significantly more RAM than the required minimum will be necessary. Memory speed has a small affect on simulation time and typically 1333 or 1600 MHz memory is adequate.
Simulation time on Windows and Linux is comparable. Users may choose whichever operating system they prefer.
Users who wish to customize any of the subroutines that Flow Science distributes as part of the standard installation will need a license for the Intel Fortran Compiler 2016. Users running Windows operating system will also need Visual Studio Professional Edition 2010 or Visual Studio Professional Edition 2013.
