Since October 1st, 2014, FLACS v10.3r2 has been available. It is delivered for Microsoft Windows and for Linux. FLACS v10.3r2 has been tested on the following platforms:
- Windows XP
- Windows 7
- openSUSE 11.1, 11.2, 11.3, 11.4, 12.1
- CentOS 5.x, 6.x
- Ubuntu 9.04, 10.04, 10.10, 11.04, 11.10, 12.04
- Fedora 12, 13, 14, 15, 16, 17
- Debian 5, 6
Red Hat Enterprise Linux 5.x and 6.x is expected to be FLACS v10.2r2 compatible since it is compatible with CentOS 5.x and 6.x, respectively.
- Processor architecture: x86 (32 bit), AMD64/Intel 64/x64 (64 bit). Intel IA64 is not supported.
- Internal memory; 2GB or more recommended.
- Free hard drive capacity: 350 MB for software installation and typically 100 GB of simulation space.
- Graphics card using NVIDIA chip set. Graphics cards using for instance ATI or Intel chipsets are generally not supported.
- DVD-RW drive recommended.
- High-resolution colour screen (minimum 19", 1600 x 1200, 24 bit color depth).
- 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.
