Been using paraview for a long time (probably going to regret saying that). Anyway, I have a cell-data only solution on a cgns mesh.
Firstly, I want to plot over a line on the mesh and see only the data from the cells: not edges, points, or from interpolation in the graph window.
Secondly, when I’m happy I have the plot I want, I want to save the data to a csv.
I cannot for the life of me get this to work, unless in the plot over line section: Attribute type is “Point Data” which places data points on the graph that are not in my solution. Changing to “Cell Data” what I would assume I should use, gives an empty plot. Likewise, when saving the data, either with the Point/Cell Data attribute set, if I pick anything but Point Data in the csv dialogue box, I get empty an csv files.
I am really sure I used to be able to do this. I’m trying to find a problem and I’m looking for subtle inconsistencies, having interpolated solution data added (useful in some instances I grant you) is not what I want at present.
Finally, for a bonus question if the above gets resolved, what interplay does the resolution dialogue box then have when one only wants to plot the actual solution data (cell-centered in this instance) from the simulation and not interpolated data? I have about 65 cells along the plot over line vector, stretched in a boundary layer. Currently, I always leave the default to 1000, so clearly there will be repeated data if I pick “Cell Data”, is that correct?
Any help really appreciated. Latest version of paraview. Hopefully this is just a simple mistake by me…
