Supported Platforms

FLOW-3D/MP runs on both Workstations and clusters (which may consist of a group of similarly configured Xeons® or Opterons®) running 64-bit Red Hat Enterprise Linux 6 or 7 or 64-bit SUSE Enterprise Linux 12, a network interconnect such as Gigabit Ethernet or Infiniband, and a large shared NFS disk accessible from all nodes in cluster. FLOW-3D/MP supports Intel® MPI, which is provided as a part of the installation. For hardware recommendations, please contact our sales team.

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.

Graphics Support

FLOW-3D/MP 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.

Memory and Processor Speed

A minimum of 4GB of RAM is recommended per processor core. For example, a compute node with two 8-core CPUs should have at least 64 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.

Developer Tools

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 and Intel MPI 5.1.
