[Paraview] Line plot with cell data: PlotOverLine ?

[Francois Beaubert]

Thanks Andy for your kind answer. 

I follow the same path as yours with two slices but sadly can't go any further. 
But perhaps someone can help us to overcome this obstacle 

Be sure that I will share the solution if I found one :) 

Thanks again.

The plot over line filter only interpolates at the specified points so it will always have point data output for the plot. You can try using two slice planes that intersect at the location of the line and then maybe some cut filters to get rid of the rest of the line that's not wanted. I'm not sure of the details of how to turn this into a plot view in paraview with discontinuous values. If you figure that step out, please share it since I was trying to do similar things but didn't get to figuring out the last step in the process.

Andy

Hello, 

I would like to see my finite volume mesh resolution in a line plot (OpenFOAM data). I would like to use the PlotOverLine filter or something else that can plot : 

* only the cell center values when inside the internal mesh 
* the boundary face values when on the computational domain boundary 

I've tried to use the PointDatatoCellData filter before using the PlotOverLine filter but it doesn't change anything for me and I don't know if it's the best procedure to accomplish this. 

Basically, I just want to have a line plot with the same number and values as the cell centers when inside the internal mesh + 2 face centers if the line cross the domain boundaries. 

Is it possible to use some filters in addition to PlotOverLine or something else to obtain this behavior ? 

Any help will be warmly welcome 
Thanks 


François,
