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
