Hi all,

In order 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

Hi,

You can sample data with sample application and play with interpolationScheme and sampling definition. When I want to see mesh resolution, I choose interpolationScheme cell; and type face; which gives me value on every face intersection.

You can find pretty much everything in "applications/utilities/postProcessing/sampling/sample/sampleDict"
