Tracking and plotting residuals while running the case about butterfly HOT 4 CLOSED

💯 for value tracker! will be very cool!

@mostaphaRoudsari Did you have a chance to look into the pyFoamPlotRunner.py utility? I was wondering, in case we can't already use it directly in windows, if we could use the rational of its implementation in BF.

Or if it's not compatible with the docker version somehow we can maybe write our parsing script to plot residuals? I think that's what pyFoam does, gets the residuals from the terminal (always printed at the same place) and charts them with gnuplot or smth. This could be cool!

If we can implement this, then we can potentially create a large amount of value trackers for a variety of situations. To give a small example, imagine an internal simulation where the wind velocity on a Z-section is important. The user then inputs the surface in Gh and we use a simple function object to calculate the average wind velocity on that surface at each timestep. We can then put a value tracker of that on the screen! To make things even cooler, we can link these kind of trackers to our stopping criteria. In the above case it can be smth like this:

IF u_track WITHIN 0.01 FOR 500 iterations THEN stop running

This is just one of the cool options! I can sit down and write all the tracking function objects OF offers and we can display and use them in the same way!

Let me know what you think!

Kind regards,
Theodore.

Getting somewhere with this one:

Also, I had a closer look to pyFOAM. Unfortunately, we won't be able to use it directly from IronPython but we should make sure that users can initiate their own pyFOAM scripts from inside Grasshopper.
