Is it possible to run a simulation of water coming in to an empty tank (just air inside) for transient flow? So essentially i can animate the water rising and coming out the outlet.
Thanks for any help |

Thanks for replying.
I want to model the tank for transient flow when initially the tank is empty and fills up with water. I've specified two fluids water and air and set initial conditions to water volume fraction 0, air volume fraction 1. The inlet is set to 5ms^-1 and the outlet to static pressure 0 Pa (inlet and outlet are at the top of the tank). Whatever i try i end up with the tank's absolute pressure at interval 1 being the same as the last interval which makes me think the tank is full of water the whole time! Have you any advice how i can model it like this? I've been through most the tutorials and have tried to use them as best as i could but im still getting weird results! Any help you can offer would be greatly appreciated! Thanks in advance |
