Hello , everyone !
I found a Physical Anomaly in tutorials/interFoam/laminar/damBreak case ! I didn't modification any other thing except for the regions in setFieldsDict ! That is : regions ( boxToCell { box (0 0 -1) (1.1461 0.292 1); fieldValues ( volScalarFieldValue alpha1 1 ); This just fill up the tank about halfway with water. Then began to compute. Certenly, it is in a condition of rest ! So the Pressure and Velocity should be arround zero . But I found the wave amplitude of Pressure and Velocity is bigger and bigger in the course of time! Though the amplitude of Pressure and Velocity is still very small, it becomes bigger when there is no energy input ! I think it is a wrong numerical result! could you help me ? How to solve this problem! thanks! |
