Since July 27, 2015, FLACS v10.4r1 has been available. It is delivered for Microsoft Windows and for Linux. FLACS v10.4r1 has been tested on the following platforms:
- Windows XP
- Windows 7
- Windows 8.1
- openSUSE 12.3, 13.1, 13.2
- CentOS 5.x, 6.5, 7
- Ubuntu 12.04, 14.04, 15.04
- Fedora 19, 20, 21, 22
- Debian 6, 7, 8
Red Hat Enterprise Linux 5.x and 7.x is expected to be FLACS v10.4r1 compatible since it is compatible with CentOS 5.x and 7.x, respectively.
It is well possible that FLACS runs on other Linux distributions or versions, too. Please get in touch with firstname.lastname@example.org if you encounter problems when installing or using FLACS on a specific distribution or version.
- Processor architecture: x86 (32 bit) and AMD64/Intel 64/x64 (64 bit) are supported. Intel IA64 (Itanium) is not supported.
- Internal memory: 2GB or more recommended.
- Free hard drive capacity: 350 MB for the software installation and typically 100 GB for simulation data.
- Graphics card: a graphics card with NVIDIA chip set is recommended. Graphics cards using, e.g., AMD or Intel chipsets may work, but support and testing are limited to NVIDIA.
- For Flowvis 5, it is recommended to use the latest graphics driver version available for the target hardware. To use the 3d plot-type in Flowvis 5, a graphics card/driver that supports OpenGL version 3.3 or higher is required. If insufficient OpenGL support is detected, Flowvis 5 will still run, but the 3D plot type might not work. Installing a recent graphics driver may solve this problem. Check the web site of your hardware vendor for relevant updates.
Points of consideration regarding running FLACS v10 on Windows/Linux:
- FLACS v10 can be run as a standalone installation on a single computer or on several computers in a network. The FLACS license manager can be installed on either a Linux server or a Windows server, and then FLACS can be run on a set of client computers consisting of both Windows and Linux clients.
- The FLACS v10 program package contains the same family of tools in both the Windows and Linux versions. If you are acquainted with Windows, but have no experience with Linux, it is probably best to start with the Windows version of FLACS v10. An experienced Linux user may utilise ordinary Linux commands (e.g. grep, find, cp, tail) to efficiently manage many FLACS simulations.
- When running the pre-processor CASD on Windows, one should take care that only one person at a time is working on the geometry files considered (to avoid errors and confusion).
- Our experience is that Linux may in some cases be somewhat more robust and efficient when several FLACS tasks demanding large resources are running simultaneously on the same computer (e.g. CASD and the Flacs simulator).
Additional requirements and comments:
- It is recommended to include all available libraries, including 32 bit versions, when the Linux operating system is installed on your computer, also when using the 64 bit version of FLACS v10. In our experience, this minimises the risk of any problems.
Support for 32 bit operating systems:
- For FLACS v10.4r1, testing has focused on 64 bit versions of all operating systems (except Windows XP). It is likely that FLACS packages for 32 bit systems will not be made available any more from 2016.
