FDS

FDS-SMV

Fire Dynamics Simulator (FDS) is a large-eddy simulation (LES) code for low-speed flows, with an emphasis on smoke and heat transport from fires.

Smokeview (SMV) is a visualization program used to display the output of FDS and CFAST simulations.

Job FSD OpenMP (single node)

Example script slurm-fds-omp.sh to run FSD on 1 node of the skl partition using 16 cores and at most 4 GB of memory:

slurm-fds-omp.sh
#!/bin/bash
#SBATCH --job-name=Modello_R04_SC1_R02
#SBATCH --output=%x.o%j
#SBATCH --error=%x.e%j
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=16
#SBATCH --partition=skl
#SBATCH --mem=4G
#SBATCH --time=0-08:00:00
##SBATCH --account=<account>
 
export OMP_NUM_THREADS=$SLURM_CPUS_PER_TASK
 
module load fds/6
 
ulimit -s unlimited
 
WORKING_DIR="$(pwd)/${SLURM_JOB_NAME}.d${SLURM_JOB_ID}"
mkdir -p "$WORKING_DIR"
cp -p "${SLURM_JOB_NAME}.fds" "$WORKING_DIR"
cd "$WORKING_DIR"
 
mpirun fds "${SLURM_JOB_NAME}.fds"

Job FSD MPI OpenMP (single node)

Example script slurm-fds-mpi-omp.sh to run FSD on 1 node of the skl partition using 4x4=16 cores and at most 1 GB of memory:

slurm-fds-mpi-omp.sh
#!/bin/bash
#SBATCH --job-name=lapse_rate
#SBATCH --output=%x.o%j
#SBATCH --error=%x.e%j
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=4
#SBATCH --cpus-per-task=4
#SBATCH --partition=skl
#SBATCH --mem=1G
#SBATCH --time=0-00:05:00
##SBATCH --account=<account>
 
export OMP_NUM_THREADS=$SLURM_CPUS_PER_TASK
 
module load fds/6
 
ulimit -s unlimited
 
WORKING_DIR="$(pwd)/${SLURM_JOB_NAME}.d${SLURM_JOB_ID}"
mkdir -p "$WORKING_DIR"
cp -p "${SLURM_JOB_NAME}.fds" "$WORKING_DIR"
cd "$WORKING_DIR"
 
mpirun fds "${SLURM_JOB_NAME}.fds"
This example uses a modest amount of memory and lasts a few seconds. For a realistic calculation it is necessary to significantly increase the required memory and the expected calculation time.

SMV

Connect to gui.hpc.unipr.it (see Graphical User Interface for details), open a terminal and run the following commands to see how to run smokeview: 

module load smv/6
 
smokeview -h
