How to establish proper computation in first time steps?
I am solving planar interface evaporation using "Multi-Fluid VOF" model implemented in ANSYS Fluent 2020 R1 Academic.
The interpolation of volume fraction field near the interface is conducted using "Geo-Reconstruct" model.
To obtain a correct solution, I have to enter "solve/set/expert" in TUI and answer "yes" on "Keep temporary solver memory from being freed?" This is preceded by one or more iterations where is this option set to "no".
The question is: "Is there anything additional that one should do in order to avoid the initial discrepancy shown in the bottom left corner in the attached figure?"
Many thanks in advance!
