Hi guys, how i can change velocity direction? That is in general settings, velocity in X positive direction, however i would like to apply wind into the opposite direction? Please help.
Do you mean you want the wind to change during the simulation run? You might need to use an equation boundary condition for that.
Or do you mean you just want the wind in the negative X direction? Just use a minus sign.
yes, just need to see wind action in an opposite direction to the original coordinates. It seems adding a minus sign worked. Thanks again.
If your external domain has no inlet/outlet boundary conditions then yes, you can just change the direction of the initial flow in the General Settings.
