Hi there,

I am new to using openFoam and I am trying to achieve some visualization for my results. I am currently using graphcell for sampling data so i can create some plots using gnuplot.

I have been able to achieve this, but i am thinking of some optimization for the way i am currently specifying the line that i intend to get data for.


here is my graphCell dict


Description
Writes graph data for specified fields along a line, specified by start and
end points. One graph point is generated in each cell that the line
intersects.

\*---------------------------------------------------------------------------*/

start (1 0.3 0.5);
end (5 0.3 0.5);

fields (U p);

axis distance; // The independent variable of the graph. Can be "x",
// "y", "z", "xyz" (all coordinates written out), or
// "distance" (from the start point).

#includeEtc "caseDicts/postProcessing/graphs/graphCell.cfg"

// ************************************************** *********************** //

the above file works and i am able to get data for the line defined by the start and end points(in red)

Since i need to observe the system at multiple lines, i intend to post process for multiple lines at the same time - such that when i run 'simpleFoam -postProcess' i get the data for multiple lines at once and i can go ahead to plot. This will make it easier to work with several mesh configurations.

My question is How do i define multiple lines in the graphCell dict?


if i cant do it in the graphCell dict , are there other ways to go about this.?
