Know Your Pump & System Curves – Part 2A
Looking to relieve pressure? Let's talk about Relief Valves in AFT Impulse.
And, Not, Or - Starting Transient Events with Complex Logic
AFT Fathom XTS and AFT Impulse have long been able to start events like pump trips or valve closures when a certain condition is met in the system. For example, a valve can close when a tank is full, or a pump can trip when the flow is too low. However, complex systems often have multiple conditions that can cause an event. The pump may trip when the flow is too low OR the suction pressure is too low. The valve may only close when two tanks are full. AFT Fathom version 10 and AFT Impulse version 7 enhance the transient capabilities to allow the definition of these complex Multi-Condition Events.

Jack, Ryan, and Sally are piloting a small research vessel on a remote river. While distracted by news of the Mars 2020 Perseverance rover (successful landing!), their vessel crashes and begins capsizing. After their initial panic, they are dismayed to find the collision has taken out their communications equipment.
In some quick thinking, Jack finds a printed log of ships expected to be nearby. Fortunately, there is a marine zoology expedition about a mile downriver, and our crew just needs to get an SOS out to that ship.
Initially, Jack tries simply yelling for help. Unfortunately, this doesn't do much good - and the explanation why requires some fluid mechanics.
