Hello i am beginner of openfoam
when i run the example related water injection from inlet, i wonder that wether the injection of water can stop or not. clearly, i think that there may be an option to stop the water injection by time in openfoam. for example, if i set the time of water injection to 0s ~50s, the time of water injection is only 0s ~50s. in other words, after 50s from starting simulation, water injection will stop. but, i did't find the option to set the water injection time. i only found the option to set the "bubble" injection time in water (constant/fvOption/points --> timeStart, duration __ i wrote the code related this in the below) [code] options { massSource { type semiImplicitSource; timeStart 0.1; duration 5; selectionMode points; points ( (0.075 0.2 0.05) ); volumeMode absolute; ~~~ and i found that if i want to inject the water from inlet to some domain, i can adjust the boundary condition of alpha.water file and U file in "0" folder. but, when i saw these files, there is not an option to adjust the water injection time unlike bubble injection in fvOption as i mentioned above. so if the time of simulation is enough long, the water always full in the domain.. (i wrote the code related this in the below ) [code] boundaryField { inlet { type flowRateInletVelocity; volumetricFlowRate constant 5; } ~~~ (there is no option like timeStart, duration) |
