How to Model Transient Flows in Ansys Fluent - Lesson 1
Nearly all flows in nature are unsteady. Although the steady-state approach is the preferred way to do CFD analysis because it is faster and easier, there are many applications where you must model unsteady flow behavior. Performing a transient calculation is similar to performing a steady-state calculation with some additional considerations: Extra inputs are required, and more data is generated. In this video lesson, you will learn when a transient simulation is necessary, and what the additional settings are for a transient simulation in Ansys Fluent, including solver settings, the specification of a proper time-step, how to save transient data instances and time-averaged results, and how to monitor convergence.
