1. Go into case_8_nuclear_room folder and give ./Allrun command
2. copy the velocity file of final timestamp(case_8_nuclear_room/(final_timestamp)/U) and replace it with case_8_art_nuclear_room/0/U
3. give ./Allrun command in case_8_art_nuclear_room folder.
   (you can change no. of cores to be used for solving simpleFoam, by Default it is kept as a 4)
4. use paraFoam command to see the final solution in the air residence time(artFoam).
