How to run fds on python?

[Андрей Х.]

Hello!

Please tell me how to edit this code to run fds on python?

import os
from subprocess import Popen, PIPE
base = (os.getcwd())
string = f"{base}/1"
os.chdir(string)
cmd = 'cmd.exe'
p = Popen(cmd, stdin=PIPE, stdout=PIPE, bufsize=0, shell=True)
p.stdin.write(rb"fdsinit\ D:\Python\Project\Repositories\Project_Clicker\Run_FDS\1")
p.stdin.write(b"fds_local -p 2 -o 1 b_1.fds")
cc = p.stdin.close()
vv = p.wait()

File.fds is located in the folder D:\Python\Project\Repositories\Project_Clicker\Run_FDS\1

[Андрей Х.]

Or maybe someone will offer their sample code to run fds in python?

Hey, buddy

Maybe you could try this for FDS 6.7, it is modified from Propti written by Lukas Arnold's group.

import os
import logging, subprocess

def generate_fds_cmd(execution_dir, model_file_name):
    root = os.path.abspath(execution_dir)[:2]
    cmd1 = 'set PATH=C:/Program Files/firemodels/FDS6/bin/mpi;%PATH% && '
    cmd2 = 'set IN_CMDFDS=1 && '
    cmd3 = '{} && cd {} && '.format(root, execution_dir)
    cmd4 = 'fds_local -p {} -o {} {}'.format(2, 1, model_file_name) # openmp and mpi
    return cmd1 + cmd2 + cmd3 + cmd4

fds_file_path = "F:/20210516-PSO-PP composite-V15/1.020_best/input.fds"
execution_dir = os.path.split(fds_file_path)[0]
fds_file_name = os.path.split(fds_file_path)[-1]

cmd = generate_fds_cmd(execution_dir, fds_file_name)
log_file = open(os.path.join(execution_dir, "execution.log"), "w")

logging.debug("executing command: {}".format(cmd))
subprocess.check_call(cmd, shell=True, stdout=log_file, stderr=log_file)
log_file.close()

Thanks, this code runs.fds and generates the execution.log file.

I couldn't figure out how to intercept and read the records that fall into the execution.log file without waiting for the end of the calculation

Then I don't know, this script is used for a relatively small model, the records seem to be useless most of the time.

If the model is huge, using Python might not be a good idea.
