What kinds of transients can the Fathom XTS Module model?
A wide range, including liquid levels, valve open/close, pump speed changes, relief valve opening and more. Just as important, the Fathom XTS module can model time transients, event transients and inherent transients. Time transients are changes that are specified to occur based on the model time. Event transients, on the other hand, are triggered by an event that occurs in the system.
Many kinds of events can be used, such as pressure, flow, velocity and liquid level. Inherent transients are changes that occur by the very nature of a system component.
Two examples would the liquid level change that occurs in a finite reservoir (or tank), while another would be a check valve opening and closing as a result of flow reversals.
