Initialize transient simulation with steady state result file with pbs script

Tingting Wu · March 7, 2019, 22:11

Hi all,

I'm trying to do transient simulations on a cluster with pbs script. But I don't know how to use the steady state results file to initialize the flow field.

The pbs script I used is: "$CFX_BIN -def $JOB_INPUT -ini-file $INITIALFILE -double -par-dist $nodes -start-method "Platform MPI Distributed Parallel"
The INITIALFILE=46005_001.res
But an error occurred: " Unknown command line 46005_001.res"

isn't it just -ini instead of -ini-file

Something is wrong with the passing of variables in the script

Try swapping the order in the command line to see which error do you get, say

$CFX_BIN -ini-file $INITIALFILE -double -def $JOB_INPUT -par-dist $nodes -start-method "Platform MPI Distributed Parallel

I've tried them both. But it worked out magically in the end without changing anything in the script. Thanks anyway!
