Hi all,


I'm trying to get a good setup for monitoring the residuals from my solve using OpenFOAM for Windows.

Typically people use foamMonitor (https://cfd.direct/openfoam/user-gui...hs-monitoring/), gnuplot (Tutorial of how to plot residuals !), or PyFoam (pyFoamPlotWatcher.py; Using pyFoamPlotWatcher.py To Plot Residuals)


However! I can't get any of these to work inside windows.
So far the best I can do is open the residual.dat file in excel and update manually.


Any suggestions on a nicer tool to use? Perhaps a python script for plotting?

Greetings Thomas and welcome to the forum!

Please provide more details to which "OpenFOAM for Windows" installation instructions you've followed.
I ask this because nowadays there are 2 to 5 different ways to install OpenFOAM on Windows... and each will have a different way to install PyFoam...

Best regards,
Bruno

Hi Bruno! Thanks!


I'm using OpenFOAM4Windows v1806.0 (using docker), on windows 10.
I've got python 3.7.0 installed via PyCharm IDE with the PyFoam 0.6.10 package.

Update: As a work-around I've gotten excel to do the plotting for me.

I've used the "Get External Data" > "From Text". From here, I've used tab separated text columns, and plotted the columns on a scatter plot.


Seems to work alright for a windows hack!

Quick answer: If you still want to use PyFoam for plotting the residuals, then please run the following script and provide its output:

pyFoamVersion.py

It will tell us what features are available and which aren't.


Furthermore, what error messages do you get when you try to run PyFoam's plotting scripts?

hello

I have exactly the same issue: the only way for me to plot residuals is through excel from the dat. files.
I have spent days to try making it with foamMonitor, gnuplot, pyFoam but no success at all !

I have installed PyFoam using pip3

#
$ pip3 install PyFoam
Requirement already satisfied: PyFoam in ./.local/lib/python3.8/site-packages (2020.5)
Requirement already satisfied: numpy in /usr/lib/python3/dist-packages (from PyFoam) (1.17.4)
#

and this is what I got when asking for pyFoam version:

$ pyFoamVersion.py
Traceback (most recent call last):
File "/usr/local/bin/pyFoamVersion.py", line 4, in <module>
__import__('pkg_resources').run_script('PyFoam==20 20.5', 'pyFoamVersion.py')
File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 667, in run_script
self.require(requires)[0].run_script(script_name, ns)
File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 1452, in run_script
raise ResolutionError(
pkg_resources.ResolutionError: Script 'scripts/pyFoamVersion.py' not found in metadata at '/home/<USER>/.local/lib/python3.8/site-packages/PyFoam-2020.5.dist-info'
#

would you have any idea of what could be the problem ?

I am running OFv2012 on Unbuntu 20.04 LTS wl2

many thanks
