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.

Available versions of FDS in ULHPC

To check available versions of FDS at ULHPC type module spider abaqus. The following versions of FDS are available in ULHPC:

# Available versions

phys/FDS/6.7.3-intel-2019a

Interactive mode

To try FDS in the interactive mode, please follow the following steps:

# From your local computer
$ ssh -X iris-cluster

# Reserve the node for interactive computation
$ salloc -p interactive --time=00:30:00 --ntasks 1 -c 4 --x11

# Load the required version of FDS and needed environment
$ module purge
$ module load swenv/default-env/devel
$ module load phys/FDS/6.7.3-intel-2019a

# Example in fds 
$ fds example.fds
