Fluent switch from implicit to explicit...

flowinflow

I'm running steady state simulation using density-based solver in ANSYS-Fluent
for a 2D airfoil in buffet condition.

I found that when I switch from implicit time stepping to explicit multigrid time stepping,
the FAS cycle always re-initialise the solution, rather than continue with the semi-converged
solution from the implicit time stepping.

Anyone has a clue how to avoid the re-initialisation?
