OpenFoam log file monitor

Hi guys,

I uploaded an early version of my log file monitoring tool to my github page https://github.com/greole/foamMon . The tool aims to give an overview of
the progress of long running simulations. Feel free to try it out.

Cheers,
Gregor

If you're interested I just released version 0.2.2, available on github and Pypi. The usage has changed slightly. To start it just run foamMon in any Simulation (or parent) folder. Tester and feedback are welcome.

You are using pip version 8.1.1, however version 18.0 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

Hey Rodrigo,

thanks for giving it a try. Can you run

Code:

~/.local/bin/foamMon

...well, here is my output:

me@work:~$ .local/bin/foamMon

Unfortunately, I do not (yet) speak Pythonian... :o

Ok, it seems that ~/.local/bin is not in your $PATH variable. What distro are you using or do you use any virtualenv like conda? Sometimes simply opening a new shell helps otherwise add a

Code:

export PATH=$PATH:$HOME/.local/bin

to your bashrc.

Regarding the urwid error, I forgot to add urwid to the depencies. After running

Code:

python3 -m pip install foamMon --upgrade

it should hopefully work.

Great, this worked. "foamMon" is now installed and it can be called.

BTW: conventional Ubuntu 16.04 installation.

So, let's keep going step by step... (that's why I put it in a separate post) ...first running issues:

As I said, I am not an expert in Pyhon, but I noticed that the errors correspond to code lines of the type:

Code:

from .<filename-starting-with-a-dot> import <some-class>

Furthermore, it searches files at

Code:

/home/me/.local/lib/python3.5/site-packages/foamMon-0.0.0-py3.5.egg/FoamMon/

(foamMon-0.0.0-py3.5.egg is not a directory) that are actually in

Code:

/home/me/.local/lib/python3.5/site-packages/FoamMon/

If you have a github account we could move the discussion to https://github.com/greole/foamMon/issues

Regarding the import issue: Could you remove the /home/me/.local/lib/python3.5/site-packages/foamMon-0.0.0-py3.5.egg folder, and try again?

Hi Gregor,

I've just tried it again at home from another machine (Ubuntu 18.04) and everything works fine finally. I will debug myself the installation in my other machine after the weekend, so don't worry anymore for it.

Installation steps for the interested reader:

Code:

python3 -m pip install foamMon

Warning: If you are using Ubuntu, it is currently not a good idea to update pip from pip (despite pip's suggestion)

add following line to the .bashrc file (Gregor, you may want to add this step to the instructions in the repository README file):

Code:

export PATH="$PATH:$HOME/.local/bin"

Note: Don't forget to reload the bash profile (or simply open a new terminal) after doing it.

... and that's it. It is a small great tool! Quite intuitive and useful. Just 2 questions:

- What does "Writeout" indicate? it looks like how long it would take to fill up the storage capacity at this writing rate... is it right?

- What does "Press (T) to toggle active" does? I keep pressing it (both "T" and "t") but it seems to have no effect.

Thanks again Gregor for the help! :)

PS: Is there any administrator among the readers willing to move this thread to the Community Contributions section?

Hi Rodrigo,

thanks for your feedback und for testing.

- "Writeout" is the estimated time till a new timestep is written to disk.

- "T" should hide all cases that are currently not running. I think it is not active at the moment.

Currently there still some bugs and rough edges, which I'll try to fix over time.

Cheers,
Gregor

Ok, since I cannot move this thread, I created a new one https://www.cfd-online.com/Forums/op...tml#post707259
