Hello,
for my simulation I need to add torque and thrust to certain cells. I set my mesh up, so I got those cells and need to add these volumeForces there and I don't have any idea, can anyone help me? |

So you have the cells already defined as cellSets?
fvOptions is your friend. |

I have the cells as cellZone.
Is there any tutorial on how to do it like syntax etc? |

There is a bad example in:
Coded Source You need to change selectionMode from all to cellSet and add another line to give the label to the cellSet: Code:
type coded; selectionMode all; fields (h); name sourceTime; Code:
type coded; selectionMode cellSet; cellSet bananaSet; fields (U); // possibly others name sourceTime; Code:
heSource[i] += 1e5*sin(200*cellx[i])*V[i]; |
