- in-simulation: this is postprocessing that is active during simulation. When running a solver, it allows for real-time data analysis and adjustments based on the simulation's current state. See below to see how you can activate in-simulation postprocessing.
- post-simulation: this is postprocessing that is done after the simulation is completed. It allows for detailed analysis of the simulation results, including data extraction and visualization based on the results that are stored in time-folders. If you want to use post-simulation, you need to run utility `postprocessPhasicFlow` in terminal (in the simulation case setup folder) to run the postprocessing. This utility reads the `postprocessDataDict` file and performs the specified operations on the simulation data.

**IMPORTANT NOTE**
in-simulation postprocessing is not implemented for MPI execution. For post-simulation postprocessing, you can use the `postprocessPhasicFlow` utility without MPI, even though the actual simulation has been done using MPI.

This is very good for particle tracking purposes or when you want to analyze specific particles behavior over time.</td> |
