Paraview time scale
 

Hello!
I have a question regarding time units and time scale in post-processing in Paraview.
I am running an OpenFOAM solver (chtMultiRegionSimpleFoam) with the following time controls:
- Start Time: 0
- Time Step: 400
- End Time: 4e+06
- Write Interval: 4000

Each time frame in Paraview represents what real time in simulation? For example, the time frame 100 represent which time?

Thank you!
