Hi all,

I am curious about certain aspects of particle tracking method available in Ansys Fluent. First of all, let me quote a sentence from Fluent Help “The Discrete Phase Model utilizes a Lagrangian approach to derive the equations for the underlying physics which are solved transiently. Transient numerical procedures in the Discrete Phase Model can be applied to resolve steady flow simulations as well as transient flows.”
In my case, flow simulation is in steady state and would like to use the DPM model (one way coupling) for particle tracking. But as stated in Fluent help, the numerical procedure for DPM is inherently solved in a transient manner (i.e., with respect to time). So in that case, in what aspect does the steady and unsteady particle tracking methodology vary with each other? Is it just that with unsteady particle tracking, it’s possible to know the position of each particle in the domain with respect to time? Or is there more to it?
