Flute role in Swarakalpana/Neravu [Carnatic]

I am performing in a kacheri with both violin and flute accompaniment. This is my first time doing neravu/swarakalpana with both instruments. What is the process? Do I sing one neravu, then violin, then flute, then me again, or should it alternate between violin and flute? Or something else?

Same question for swarakalpana. How does it alternate? Especially when it comes to thaggimpu/korippu, it doesn’t make sense to me that both instruments would go.
