OpenFoam - Paraview: Extract Data for All Time Steps

[@hemanthHK11]

Thank you soo much Asmaa Hadane :) , I was the one who asked this answer... It helped a lot... Thank you .... Keep going

[@ulissesjesusgutierrezherna6318]

Thanks so much! I didn't even know this i what I was looking for :)

[@wikie23]

perfect, exactly what I was looking for

[@lukefairbanks8622]

one of the first tutorials I've seen done by a woman haha respect :)

[@cianwarby6157]

Thank you so much this was exactly what I was looking for and very clear!!

[@HarsimranSingh-e9o]

Is there any way to extract data of all the time steps in one file, instead of separate files? Thank yo.

[@locorocozhong3941]

Thank you for sharing this useful technique!

[@souravganguli8521]

Thank you very much for this great information

[@adamczykj89]

Thank, very useful video

[@DonHickory]

Thank you so much!😁

[@youssefph-c0916]

thank you it was very useful.

Hi, Thanks for your video! It helps me a lot. I have one question: if we have 4000 time steps and 90,000 cell points in a structure.... how to extract all quantities at each time step at each node in one file and get all the output files of different nodes in one folder？ The nodes in my structure are too many, so selecting each node over and over again will waste a lot of time. Are there any simple methods? Thank you.

Thank you!

I would like to know if it is possible to generate the average of the results. In 'controldict' I changed the 'functionObject' to find the Cp, but I couldn't generate the average. Thanks.

[@CFDAsmaaHadane]

You can average the field of your interest using the function object fieldAverage in the controlDict file. Below is an example of velocity averaging, you can apply the same thing to pressure, temperature...
/*********************************
functions
{
fieldAverage1
{
type fieldAverage;
libs ("libfieldFunctionObjects.so");
writeControl writeTime;
fields
(
U
{
mean on;
base time;
}
);
}
}

Thank you! Very useful!

[@TheGreatAquiles]

Thank you for this !!!

[@adrianBM99]

Hi , thank you very so mucho for the video was very useful!. I have a problem regarding the values that appear un the table, the simulation is running and working but then in the velocity column appears NaN. Do you what can happened?

[@amandaborgesdealmeida2922]

Thank you soo much.
Is it possible to extract the average alpha values ​​at each time step in a simulation with interFoam?

[@CFDAsmaaHadane]

It is much easier to do it in OpenFoam as a functionObject written in controlDict, then you can visualize it in paraview.

[@AhsanKhanPhD]

You are a life saver!!!

I m trying to create a Macro for plotSelectionOverTime. But, when I run Macro. It does not select data as per the selection criteria. plotSelectionOverTime runs without selecting any cells. What should i do?

[@CFDAsmaaHadane]

Open you macro file and check the name of the active selection, because if you set your macro for a specific case then you apply it on another case with other name, you may have this problem.

[@pratikpunj]

thanks a lot.

[@Tores1470]

No way of saving with the anotatted flow time? My time steps are not equally spaced and would like to track my contour over the flow time

[@sundarrajn1003]

awesome

[@sibinvmathew8501]

can we extract data from all node points?

[@CFDAsmaaHadane]

Yes you can do that, select spreadsheet view then choose Attribute: Point data and extract.

[@hemanthHK11]

One more question.... for example if we have 200 time steps and 90,000 cell points in a cylinder.... how to extract velocity or pressure or temperature at each time step at each cell point.... i mean how to get cell point/mesh point column in excel file .... as in this video. ( I am getting values at each time step like shown in this video but i am getting only through the length of my cylinder pipe)
If my question is not clear please let me know i will try right again..... Thank you and waiting for your reply. It is so important for my project please.....

[@CFDAsmaaHadane]

You mean you want to extract information in one point of the mesh.. If this is your case you need to define a probe in paraview and extract data on that probe.

[@ashok305]

does anyone know how to export paraview results (Animation) into openfoam or blender or unity

[@muhammadchoudhry5864]

what does u0, u1, and u2 represent? is it like ux,uy,uz?

[@CFDAsmaaHadane]

Exactly!

[@bridge5189]

When I try this method, it works well on Point Data but fails on Cell Data. I am using the latest version of Paraview.

[@SoorajNSaranya]

How can i get computational time in data rather than time steps?

[@nourelislamlounis3328]

tyvm

[@thanatsaisaengtham9643]

Can you show me how to use noiseDict

[@netradipakdodke2539]

How to plot pressure coefficient over airfoil

[@CFDAsmaaHadane]

Do you mean the drag coefficient?

[@netradipakdodke2539]

@@CFDAsmaaHadane No, pressure coefficient

[@CFDAsmaaHadane]

You need to set a functionObject of pressure in your controlDict, please check this link for more details www.openfoam.com/documentation/guides/latest/doc/guide-fos-field-pressure.html
