Two particular commands needs to be part of Allrun script especially if flow problem solved in multiprocessors.



reconstructPar -newTimes


This command writes results into corresponding time stamps otherwise what you will have 0/



Another command also necessarily be part of Allrun script is



simppleFoam -postProcess -func wallShearStress


This will calculate wallShearStress at the wall (no-slip) BC.



This you will U, p and wallShearStress variables available to plot in Paraview.



I literally wasted 4 weeks figuring out this for a novice.
