Hello,
I modified the pimpleFoam solver in order to add a moving source term (using moving cellSet, ...etc).
Now in paraFoam, I can see the cellSets (by checking: include sets). The problem with this is I cannot visualize the velocity contours and the cellSets simultaneously. So I decided to convert the cellSets in each <timestep>/polyMesh/sets directory to VTK format:

for timeStep in $(foamListTimes); do foamToVTK -time $timeStep -cellSet myCellSets; done

The simulation time is 1 second with dt = 0.01 (so I have 100 timesteps).
Here is the issue that I encountered:
When I open the simulation case:

paraFoam

everything works fine (In paraview, the time is normal: there is 100-time steps as expected). But when I load the cellSets from the VTK folder (while the simulation is loaded in paraview), the total time steps in Paraview changes to 200. That is when I load the cellSets from the VTK folder instead of starting from 0 it starts from 100.

I hope you can understand my problem.

P.S: I tried to convert the simulation to VTK and that solves the issue, but I am asking why that happens?

Quick answer: I'm possibly late on this, but the trick is to load the same "casename.OpenFOAM" file twice within the same ParaView:

1. In one entry, you choose the normal fields et al you want to see.
2. In the second entry, you choose to only see the desired cellSets.

The separate VTK files do not have timing identification in them, therefore they don't match the same simulation timestamps as the case itself, e.g. you probably have time snapshots every 0.5s for 100s, which results in 200 VTK files, but the ".OpenFOAM" file is open in ParaView with the timestamp identification and only goes up to 100s.
