[Python] How to run a tNavigator simulation using Python (not just launch the GUI)?

I'm trying to automate the simulation process in tNavigator using Python. So far, I can launch the tNavigator GUI using the provided Python API, but the simulation does not actually start running.



import subprocess
import time
import pyautogui

exe_path = r"D:\tNavigator\t-navigator22.4\tNavigator-22.4.exe"
model_path = r"D:\tNavigator\Project\IP14_CO2\IP14_E300.DATA"
run_btn_image = "run_button.png"

subprocess.Popen([exe_path, model_path])
time.sleep(15)

location = pyautogui.locateCenterOnScreen(run_btn_image, confidence=0.85)
if location:
pyautogui.moveTo(location)
pyautogui.click()
print("✅")
else:
print("❌")


I want to automatically run the simulation (not just open the project in tNavigator).

Ideally, I also want to:

Wait for the simulation to finish,

Check if it completed successfully,

Extract results (e.g., RSM file path, summary output).

Thanks in advance!
