Problem in sampling data

Dear Foamers
HI
I simulated a multiphase flow. After simulation completed I sampled data for drawing velocity profile. Unfortunately the sampled data are very different from what I saw in paraview.
Is there anyone know what happened to sampling?

Here you can see their comparison:

How do you define the paraview line and the sampling line for the sample utility?

Best,

Dear ALberto

I defined a line in paraview (start and end point) and then copy them to sample dict.

You will obtain the same result with sample, if you set

interpolationScheme pointMVC;

Best,
