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: Last edited by MOHAMMAD67; April 30, 2012 at 14:32. |

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,
