Fluent steady vs transient

WebHello, I am trying to simulate aeroacoustic simulation of the fan , for this, I want to Use the LES model but my Fan is running in Steady-state. As LES model is for Transient simulation in Fluent. Is there any way to Use LES for steady-state followed by acoustic stimulation. Any suggestions are appreciable . Thank You WebMar 17, 2024 · Also, a steady state establishes after a specific time in your system. However, a transient state is essentially the time between the beginning of the event and the steady state. Therefore, in terms of a definition, a transient state is when a process variable or variables changes, but before the system reaches a steady state. Also, …
