fanta Member Join Date: Oct 2011 Posts: 56 Rep Power: 15	Hi, i am new to this kind of postprocessing. Having the same geometry of a flat nozzle depending on it's mesh i get different results for the fluid velocity at the nozzles exit with the plot over line tool in ParaView. So, with OpenFOAM's sampling postprocessing tool i might also calculate the fluid velocity at the nozzles exit (along a line) plus i have interpolation schemes. What way is the correct one? ParaView plot over line or sampling with OpenFOAM? Mesh is tet dominant. Thanks, fanta
