Hi Cyprien, thanks for making this video. It was very helpful in showing me how to extract data from a flat surface that I could then further process. Cheers, Bob, UK.
great info. Thanks bro. One query, when you create a custom variable(say q_x) using calculator and do plot selection over time, in the spreadsheet view, it shows like avg(q_x), max(q_x) etc but no where as q_x, so which one to use for time verses q_x plot in my project?
Hi @Cyprien, please I need a little help to plot a variable over the circumference of a cylinder (0° - 360°), counter-clock wise if possible. How can I do that please?
Hi Cyprien, I try to calculate wall shear stress around cylinder (no-slip wall) in paraview, but it generates all zero because the velocity on cylinder wall are zero everywhere. Do you know how to extract the first layer grid cells around cylinder instead of cylinder surface? Thanks!
There’s a filter to extract a surface, so you can first get the cylinder surface and then there is probably another filter to extract all cell within a certain distance to a surface... my guess. You have to try and have a look at the filters available. Another way would be to split your geometry before calculation or create a group consisting only of the first layer of cells you are interested in. Another way would be to select the data within certain boundaries only and then extract the cells into this range with an extract value filter.
Hi Cyprien, thanks for your video!! Plot selection over time can be time-consuming for a large domain. Do you know if there's any trick if let say I'm interested in only a specific time range, can I do plot selection over a specific time period?
Thank you so much.... one question.... At the end of video where u extracted data.... can we get "at what time step" is that each point ID in spreadsheet!!!!!! please answer waiting for your answer... Thank you
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?
@@Feaforall I tried "Extract selection" and then apply plotSelectionOverTime. But, still same problem arises. It is not automatically selecting field while running the macro. Any solution?
Hi Cyprien! I plotted thousands of streamlines using stream tracer and I want to know the coordinates of every single streamline. It's just impossible to select each streamline manually to get the coordinate. Can paraview extract the coordinate data of a single streamline rather than the data of unordered points automatically?
Maybe try with python? Display the trace and try to find which variable controls the streamline position. Then you should be able to print that out in a text file
Dude, your playlist is awesome, congrats !!! I have a question, is it possible to view legend from a data selected? For instance, you select some cells from the object and want to show the stress only in those cells. Thanks!
Hello, thanks for the tutorial, very useful, learnt a lot, I am trying to run some stats on a very similar dataset, for example, how would you quantify the number of points that show plastic strain that is more than one over time
Hi, thank you so much for the video! I have saved a 3D matrix from matlab as a vtk file, so it is possible for me to visualize the data with ParaView. While using the "Find Data" option, if I select "Cell(s)' in the "Find" box I can't enter de selection criteria, it only works if I select the "Point(s)" option. The problem is that, when I extract the selection, the final image shows me only the points, but not the mesh. Do you have any idea of how I could fix this? Thank you!!
It seems like your matrix is interpreted as an array of point. To get cells, you can use a filter which extrapolate point data to cell i think... do a Ctrl+space and search for point then look at the filters available and see what works!
Hello, nice lessons. Can you make the video about mesh creation and caltulcation with Salome (FEM). I'm interested in large meshes about 1million elements with different extrudions and etc. The most important is the Mesh Algorythms and Hypotesis
Hello Cyprien. Please can you also rpovide a link of all files you are woirking on in your tutorials so that we may practice while we are watching it. Watching without practice is not effective. Thanks and keep up the good work.

Thank you very much, there is just so much to ParaView I don't know about! If only I watched this at the start of my PhD... :)
I am writing to express my deepest appreciation! Really helpful ..Thanks
Thank you for this video. Is it possible to plot surface values over time ? like fluid velocity at the inlet of a pipe.
Hi Cyprien, thanks for making this video. It was very helpful in showing me how to extract data from a flat surface that I could then further process. Cheers, Bob, UK.
A very helpful video.
Many Thanks
Great explanation , and a helpful video , well done , thank you 👍👍👍
Thanks for the tutorial, is there a way to export the selected region and make a new data set from it? Thanks!
Really Clear concise videos - and very helpful - thanks for taking the time to share and enlighten us.

You just saved my life !!!
Thanks a lot! Paraview is not so easy to learn by yourself.
how can i for example save my alphawater values which i have plotted over a line in a text file? text file should include: time, alphawater value

You might have to make an automation with python to get the time step and write it back in the spreadsheet... check the python automation video

Try to use a filter such as “extract selection” instead

Cyprien Rusu Thank you so much!
Very useful, thank you!
Hi dear, it was useful thank you so much. I am working on my PhD thesis, can I ask my questions about OpenFOAM or ParaView if I had, please ?

I fixed the issue. I just selected the "Clip" option, and then I selected "Scalar" in stead of "Plane". It worked perfectly. Thanks!
