in weiroverflow example, i modified some parts from original codes.
the modified parts are below. [code] boundaryField { inlet { type flowRateInletVelocity; volumetricFlowRate table ( (0 0) (100 0) (100.01 0.008) (200 0.008) (200.01 0) (300 0) (300.01 0.008) (400 0.008) (400.01 0) (500 0) (500.01 0.008) (600 0.008) (600.01 0) (700 0) (700.01 0.008) (800 0.008) (800.01 0) (900 0) (900.01 0.008) (1000 0.008) ); } originally, in the weirovercode example, water comes out constantly from inlet, but i want to simulate the time varying water injection, so i modified this part as i mentioned above. from the modified part, we can know the water injection exist only at 100~200s, 300~400s, 500~600s, 700~800s, 900 ~1000s as same flow rate (0.008m^3/s) however, as time goes, the speed of water filling increased although i set the same flow rate (0.008) in the simulation, the stop time and inject time work well. but in the inject time, the flow rate i set does not work well i think.. how can i solve this problem? .. |
