pyeuler3d

Python package interfacing with the awesome Euler3D CFD software

Use

Create a config object

import pyeuler3d.config as config
import os

# All config files option for Euler3D are available as keyword parameters to this class' constructor
cfg = config.config("Path/To/Your/Mesh.su2", SPEED_OPTION = config.SPD_OPTION_MACH, SPEED_VALUE = 0.8, AOA = 1.25)

# write the config to a file
savePath = "cfg.e3d"
cfg.write2file(savePath)
with open(savePath) as configFile:
    print(configFile.read())
os.remove(savePath)
