Hi,
I need to implement a pressureGradient force for spray parcels. I want to simulate gas parcels into a liquid using sprayFoam. However, pressureGradient force needs a dictionary, and I have not been able to find an example of such a dictionary. Can anyone provide an example, please? Thanks |

Voila!
Code:
particleForces { gravity; pressureGradient { U U; }; } |
