So i understand if im reading yor ORSI right or not, it looks like the top green box says 0.03257_1.0% at 1291i would this mean i should stop at 1291 for your tests?
the bottom also shows this. this i assume means the start of 1% stable (green line)
Edit i see this is where the 1% starts so i need to pick a point after this
What is the Moving average filter iterations? is this within your ORSI program?
For quick test, you can stop early just by using the Quick approach I just showed…
For through test where you want to have final iteration results match ORSI values at the last iteration, you have to look at the ORSI at last iteration:
.
.
ah ok so
Correct?
That works as long as last iteration at 487 continues to matches ORSI at 487 (if you want to look at interim solution set plots and yPlus))…
But at the end, you need to do a the same process at low ORSI % 500i and a large enough moving average iterations that get rid of the oscillations…
EDIT: Also, the reason you only go to 500 in the first place is because you had previously made a long run that showed that 500 was already in the stable oscillating range as shown here…
AND actually, the 500 stage could be skipped too if you could see that at 487 the result matched the long iteration ORSI 500i large moving average iterations value…
It comes down to, at some point in time, you will have to do 2 (maybe 3) long iteration runs before you can hang your hat on having the solvers best guess data at the last iteration and at the ORSI you want at that last iteration…
I am going to keep presenting all results of my 01357 layer testing, in this topic, as the results come in…
First I easily created a 1909728v 0 layer mesh with the exact mesh setup as 1 and 3 layer meshes… This should give a valid comparison of 0 vs 1 vs 3 layers…
Here is the ORSI values for that 2718 iteration run:
If we set the Moving Average iterations to 2, we can see that ~20% data range in this ORSI plot:
In any case, before I start having 3 and more images to cycle through to show the flow pattern changes between the various number of layers that I end up analyzing , I will simply look at the ORSI results for them in a table…
Here is the table so far for 0 vs 1 vs 3 layers:
.
And according to my preliminary 5 layer mesh I think 1 layer be may even be more ‘in the game’ when I present that new table with a 5 layer mesh added (the 5 layer mesh should be expected to give better results than the 3 layer mesh, if I do it right)…
But to do a good 5 layer mesh on the geometry, I have to change the geometry a little and the refinements a little, so I will have to redo the whole series of meshes with the new geometry and refinements to have a valid table, but I think that is worthwhile here 
I think what is mainly happening here lately is that we are developing a way to analyse the sim results such that we are presenting results that most closely represent the ‘best guess’ of the solvers given our potentially flawed input to them …
We have also tried to layer and simulate your geometry in a way that the solvers ‘best guess’, is ‘possibly’ close to what the real world results would be, if we could even measure them…
So I think there are two distinctly different educational threads occurring here 
this is indeed getting crazy. I wish i was up to speed on how to use and your ORSI effectively. I had the Y+Histogram file in my downloads folder but i dont think it connected to the sim outputs. Can i used ORSI after the sim is run or does it have to be done while the simulation is running?
Yes after OK too, are there CSVs in your downloads dir and does the button go green when you click on ‘Begin monitoring’?
Do i have to make the Y+ histogram plot first? as in extract the CSV data in paraview? Can i change where the file looks, as in not the downloads directory but where i saved my FOAM.data file?
PS here is the results from the 3.2mm 1 layer test
Very nice (except for 8-20 (will be interesting to see the ORSI difference))…
Click on red ‘Monitor incoming plot data’ button and then the ‘Begin monitoring’ button that appears…
Then, on any plot in SimScale click on download csv…
Why do you NOT want to use 3.4mm 1st layer?
That is new error I will research… did you get errors during using the setup file? You need to run my setup.exe at least once to get richtx32.ocx registered…
Its not that i dont want to use 3.4. I just thought if the lowest we could go was maybe 2.8 or something then we could fit a second layer and get the best of both worlds
I have run it already, i can try it again and see if that works
Any chance you have a 32 bit computer?
pretty sure i dont, im running the new paraview wich is 64 bit
Most likely the ocx didn’t register, here is a debugging thread for that, I know the setup zip should include the ocx, then we just need to get it registered and then find out why it did not register when setup exe was run…
Otherwise it is something else 
causing error…
