Running the open-source Fire Dynamics Simulator FDS on the CHPC system
Introduction
Please refer to the FDS home page for more information on FDS, an open-source code targeted at fire simulation. The current version of the code is 6.7.0, and has been installed in '/apps/chpc/compmech/CFD/FDS'. There is a module for FDS installed on Lengau. module load chpc/compmech/FDS/6.7.0 will set up the appropriate environment.
Sample PBS script
- runFDS.qsub
#!/bin/bash #PBS -l select=2:ncpus=24:mpiprocs=8 -q normal #PBS -P MECH1234 #PBS -l walltime=6:00:00 #PBS -e /home/jblogs/lustre/FDS_Runs/stderr.txt #PBS -o /home/jblogs/lustre/FDS_Runs/stdout.txt export PBS_JOBDIR=/home/jblogs/lustre/FDS_Runs cd $PBS_JOBDIR module load chpc/compmech/FDS/6.7.0 export OMP_NUM_THREADS=3 nproc=`cat $PBS_NODEFILE | wc -l` mpirun -np $nproc -machinefile $PBS_NODEFILE fds FDS_inputFile.fds > fds.out
Postprocessing
Smokeview is also installed on the system, and can be accessed with the command smokeview or smv. However, this is only possible when using one of the visualisation nodes chpcviz1 or chpclic1. Please read the instructions on setting up a VNC connection, and run Smokeview with the VirtualGL wrapper /opt/VirtualGL/bin/vglrun smokeview. It may also be practical to use the very well-developed visualisation codes Paraview or VisIt. Please experiment and provide feedback.
