Hello,
Is anyone know how can I find the total volume of air in the the domain for an exact time after simulation finished? I mean when simulation finished, I would like to see, for example, how much air stays in the domain at the time 15 sec. Accually how air volume changes in time. I am using OpenFOAM 4.1 and water and air are the fluids in the domain. Thank you, Yasemin |

Just add this block to controlDict:
Code:
functions { waterVolume { type volFieldValue; libs ("libfieldFunctionObjects.so"); log true; writeControl writeTime; writeFields true; regionType all; operation volIntegrate; fields ( alpha.water ); } } I didn't test it myself but it should work. You can find more info here. |

Hi Taataa,
Thank you so much for your reply. I have added it to the controlDict but it gives error as is seen below. Do you have any idea about it? Quote:

Try changing regionType to cellZone and name to all.
Code:
functions { waterVolume { type volFieldValue; libs ("libfieldFunctionObjects.so"); log true; writeControl writeTime; writeFields true; regionType cellZone; name all; operation volIntegrate; fields ( alpha.water ); } } |
