FLOW-3D CAST is supported on 64-bit Windows and Linux platforms.
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 SUSE 12
Support for users who have installed FLOW-3D CAST 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.
nVidia Quadro series graphics cards are highly recommended, and are ideal for Windows machines which will be accessed remotely. nVidia’s GTX series has shown decent performance on desktop and notebook machines but is not recommended for remote visualization.
Certain graphics implementations are blacklisted and will result in degraded graphics and/or unreliable performance. The following OpenGL renderers are neither recommended nor supported:
- Intel integrated graphics
- GDI Generic: This is the Windows default renderer when FLOW-3D CAST is opened via Remote Desktop Connection.
- Mesa: This is a common default implementation for Linux machines.
- Gallium: This is a common default implementation for Linux machines.
License Server Software
FLOW-3D CAST 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, Server 2008, or Server 2012 and you must use a hardware key (dongle).
Memory and Processor Speed
A minimum of 4GB of RAM is recommended per processor core. For example, a workstation with two 6-core CPUs should have at least 48 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.
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 2013. Users running Windows operating system will also need Visual Studio 2010.
