how can plot velocity profile on an airfoil over a line?
i am simulating the flow over an airfoil, i done my simulation with openFoam, and now i wanna plot the velocity profile over a line that is approximately perpendicular to the surface of airfoil, at trailing edge.
what should i do?
P.S. i use paraview for postprocessing the results.
Thank you very much.
In paraview you could use the "plot over line" filter. Optionally, you can use the OF sampling utilities. There's quite a lot of info in this link and the tutorials it mentions:
how two plot vlocity profile on the airfoils in the airfoil??
hi dear all
i am simulating the flow on an 3 element airfoil, now i want to plot the velocity profile at the different stations on the airfoil, as like as the pictures in the attachment, could you please give me some suggestion how i can plot this figure?
contour plot of turbulent intensity in paraview
Dear Foamers, i need a help!
i want to plot the contour of turbulent intensity on my airfoil, somthing like the picture in the attachment, i don't know how can i do it, can any body guide me?
Thaknk you very much.:)
first of all i load the VTK of my file, then i select the plot over line in direction of y axis then i hit apply, i doesn't show my any thing in it's figure,
Sorry, can you guide me more:o
You got it right, not sure what your problem is to be fair. Here's a step-by-step of how I do it:
1. load your case to apraview using paraFoam
2. add the plotOverLine filter, in Display tab of the object inspector mark the thing you want to plot (my example is for pressure)
3. hit apply and a figure should appear on the right hand side showing a plot in the line coordinate system
Your problem might be that either you didn't load the data to paraview but just the mesh or you have nothing selected in the display tab I think.
If you want to plot the axial components of velocity and not just its magnitude you may use the Calculator filter first, select the result to be the U_X scalar and then apply the plot over line to it - without doing this you would only be able to plot the magnitude of U.
Let me know if that helps.
P.S. depending on what you want to plot, you might also look at the OpenFOAM probe utilities which allow you to sample over a surface. You can then easily read the data into Python, Matlab or whatever and make nice plots there. If you want to plot the Cp over your foil that's probably the better way to do it.
Greetings to all!
@Saeideh: Sorry for taking so long to answer to your questions, but my to-do list here on the forum is getting bigger than the time I have available :(
I moved a couple of posts you had made on other threads into this one, because they are all related, one way or another. So, in order:
This is a pretty tricky thing to do in ParaView. Let's see:
Then it's just a matter of doing the same for all other stations.
Mmm... I was planning on taking care of another reply here, but it's best to answer where you had asked it, namely here: http://www.cfd-online.com/Forums/ope...tml#post468745 post #15
