Hello Foamers,

I am running a dambreak case using interfoam solver. I have 2 boxes dams, (box1 and box2) set by setFieldsDict. I want to box2 to start flowing after sometime, say after 2 seconds. Is there any easy way to do so?

So far I tried using fvOptions to fix velocity for box2 and managed box2 not to flow. Can I fix velocity for certain cells for only for the first few seconds, say 2 seconds using fvOptions?

The fvOptions I used is:
    type            vectorFixedValueConstraint;

    selectionMode   cellZone;
    cellZone           zone1;
      U   (0 0 0);      // I want this work only for the first 2 seconds
