FLUENT is run in parallel, each partition builds its own ISAT table and does not exchange information with ISAT tables on other compute nodes. You can save the ISAT tables on all compute nodes:
Each compute node writes out its ISAT table to the specified file name, with the node ID number appended to the file name. For example, a specified file name of
my_name on a two compute node run will write two files called
Subsequent runs can start from existing ISAT tables by reading them into memory.
Files can be read in two ways:
Parallel nodes can read in corresponding ISAT tables saved from a previous parallel simulation. The appended node ID should be removed from the input file name. For the above example, the file name
my_name should be specified in the
Select File dialog box. You should never read ISAT tables generated from a parallel simulation with a different number of parallel nodes.
All nodes can read one unique ISAT table. You might use this approach if you have a large table from a serial simulation.
FLUENT first checks to see if the exact filename that you specified exists, and if it does, all nodes will read this one file.
