We are going to simulate Air residence time in the MFHT room at the IIT Bombay.
here we use the simpleFoam k-epsilon model for flow velocity simulation and artFoam for air residence time simulation To successfully run the simulations you can follow the following steps:
step-1:Please download the case file namely 'velocity' and save it to your run folder in OpenFOAM.
Step-2:Go to your terminal and go to your run folder
Step-3:by using the "cd" command go into the 'velocity' folder. Then type the "bash ./Allrun" command in your terminal.
Step-4: After a successful process, you can visualise results in the ParaFOAM.

For setting the artFOAM solver follow the below steps.
Step-1:Download the 'artFoam' folder and save it to your run folder in OpenFOAM.
Step-2:Go to your terminal and go to your run folder.
Step-3:by using the "cd" command go into the 'artFoam' folder. Then type the "wclean" and afterwards "wmake" command in your terminal.


For running airRT (air Residence) follow the below steps.
Step-1: Download the 'airRT' folder and save it to your run folder in OpenFOAM.
Step-2: Go to your terminal and go to your run folder.
Step-3: Copy the latest velocity file (U) from the 'velocity' folder and paste and replace it with the '0' folder in the 'airRT' folder.
Step-4: by using the "cd" command go into the 'airRT' folder. Then type the "bash ./Allrun" command in your terminal.
Step-5: After a successful process, you can visualise results in the ParaFOAM.
