Dear Fellows

Its a while that I am using Paraview for post-processing my Foam based results. However, I hadn't noticed this issue before, probably because I did not need it.
I have made a roughly 1 dimensional grid with the length of 10 in X direction (desired direction). In blockMeshDict I have used the value of 1400 for the edge between first and last points in X direction. So, I expect each cell has the length of 10/400 ( =0.00714 ) in X direction. When I use the 'plot over line' filter in x direction for plotting a variable (for instance, phi), I expect to have 1400 data on my line. However, paraview just gives me 101 points, which is significantly lower than what I expect.


Why this happens? Is there any way to exploit 1400 data along X axis as I have mentioned for the devisions between first and last point (1400 cells in X direction) in blockMeshDict file?

This snippet in my blockMeshDict shows that I have 1400 cells in X direction:

vertices  #codeStream
{
    codeInclude
    #{
        #include "pointField.H"
    #};

    code
    #{
        pointField points(8);
        points[0] = point(0,  0,       0);
        points[1] = point(10, 0,       0);
        points[2] = point(10, 0.05,    0);
        points[3] = point(0,  0.05,    0);
        points[4] = point(0,  0,    0.05);    
        points[5] = point(10, 0,    0.05);
        points[6] = point(10, 0.05, 0.05);
        points[7] = point(0,  0.05, 0.05);

        os << points;
    #};
};

blocks
(
    hex (0 1 2 3 4 5 6 7) (1400 7 1) simpleGrading (1 1 1)

);

I have uploaded four files including pictures of my paraview settings and the file achieved by saving data on the desired line using 'plot over line' filter plus the blockMeshDict.


Any hint is appreciated.

Hey Foamers

I am thinking of using sampleDict to extract data along the desired line with appropriate number of points. However, still interested to find the method in paraview to use 'plot over line' filter with correct number of cells in simulation not reduced.

Any hint is appreciated.

Dear Fellows

Although you can use sampleDict to extract data, I am gonna put the answer of this question for others that may make this mistake (the same as me):

Dont forget to increase the resolution of 'plot over line filter'. Otherwise, you may keep struggling with increasing grid resolution with the same plots with paraview.

Hi Bobi,

second picture of you - below RESOLUTION 100. Therefore, you have only 100 probe points.

Yeah, I know Tobi.

Some times , I make strange mistakes.
