To run parallel
FLUENT using the graphical user interface, type the usual startup command without a version (i.e.,
fluent), and then use the
Select Solver panel (Figure
to specify the parallel architecture and version information.

Select Solver Panel
Perform the following steps:
Versions, specify the 3D or 2D single- or double-precision version by turning the
Double Precision options on or off, and turn on the
Options, select the interconnect or system in the
Interconnect drop-down list. The
Default setting is recommended, because it selects the interconnect that should provide the best overall parallel performance for your dedicated parallel machine. For a symmetric multi-processor (SMP) system, the
Default setting uses shared memory for communication.
If you prefer to select a specific interconnect, you can choose either
Ethernet/Shared Memory MPI,
Ethernet via sockets. For more information about these interconnects, see Table
31.3.2, and Table
