HOW TO RUN
------------------------------------------------------------
1. Move to the Allrun folder:
       cd Allrun

2. Run the simulation:
       ./Allrun.sh

   - This will start pisoFoam and save log files in:
         Allrun/logs/log.pisoFoam

3. Check progress:
       tail -f Allrun/logs/log.pisoFoam

4. When simulation completes, results will be stored in time folders:
       0.7, 0.8, 0.9, ..., up to endTime (as defined in system/controlDict)

------------------------------------------------------------
HOW TO CLEAN
------------------------------------------------------------
1. Move to the Allrun folder:
       cd Allrun

2. Run the cleaning script:
       ./Allclean.sh

   - This will remove all time folders (except 0/),
     delete postProcessing data, and clear logs.
