How to get the PyMechanical app.print_tree() into logger info.?

Naveen Kumar Begari

Hi team, Im trying to get the app.print_tree() tree data into the logger. Below is the script for you reference:

`import os
import logging

os.environ['PYTHONIOENCODING'] = 'utf8'

from ansys.mechanical.core import App

logger = logging.getLogger()

logger.setLevel(logging.DEBUG)

stream_handler = logging.StreamHandler(sys.stdout)

stream_handler.setLevel(logging.DEBUG)

logger.addHandler(stream_handler)

from ansys.mechanical.core import App

app = App()

app =App(version=242)

ansys_tree = ansys_app.print_tree()

logger.debug(f"Ansys Tree Structure:\n{ansys_tree }")
`

But Im unable to get the tree.

I need your assistance here..!!

Take this as reference:

`import os
import logging

os.environ['PYTHONIOENCODING'] = 'utf8'

from ansys.mechanical.core import App

logger = logging.getLogger()

logger.setLevel(logging.DEBUG)

stream_handler = logging.StreamHandler(sys.stdout)

stream_handler.setLevel(logging.DEBUG)

logger.addHandler(stream_handler)

from ansys.mechanical.core import App

app = App()

app =App(version=242)

ansys_tree = app.print_tree()

logger.debug(f"Ansys Tree Structure:\n{ansys_tree }")
`

Hi @Naveen Kumar Begari . In your code, ansys_treeis not a string. There is probably a more elegant solution, but here's one workaround:

tempfile = r'D:\temp.txt'
import sys
from ansys.mechanical.core import App
app = App()

original_stdout = sys.stdout
with open(tempfile, 'w', encoding="utf-8") as file:
   sys.stdout = file
   app.print_tree()
   sys.stdout = original_stdout

with open(tempfile, encoding="utf-8") as file:
    ansys_tree = file.read()

Hello @Landon Mitchell Kanner, Thank you so much for your response.

But,
when I execute these lines:

```python
ansys_app = App(version=242)
ansys_app.update_globals(globals())
ansys_tree = ansys_app.print_tree()
tempfile = 'simulation_logs.txt'
original_stdout = sys.stdout
with open(tempfile, 'a', encoding="utf-8") as file:
sys.stdout = file
ansys_app.print_tree()
sys.stdout = original_stdout
with open(tempfile, encoding="utf-8") as file:
ansys_trees = file.read()

So in .txt file it was reading perfect but in webapp it was showing different.

For you reference:

ansys_app = App(version=242)
ansys_app.update_globals(globals())
ansys_tree = ansys_app.print_tree()
tempfile = 'simulation_logs.txt'
original_stdout = sys.stdout
with open(tempfile, 'a', encoding="utf-8") as file:
    sys.stdout = file
    ansys_app.print_tree()
    sys.stdout = original_stdout
with open(tempfile, encoding="utf-8") as file:
    ansys_trees = file.read()

from log file I need to show on the WebApp.

@Landon Mitchell Kanner, While performing the analysis (specifically when the solver is triggered), the logger keeps disconnecting.

Is there a way to keep it active on the web app?

I am not very familiar with the logging module, which is part of Python and not developed by Ansys. What are you using to create a web app? I suggest you post a new question with enough details to reproduce the issue.

Hi @Landon Mitchell Kanner, I'm using Dash technology for webapp development.
Sure, I will post
