Why there are two types of transient studies for laminar two phase flow level set (tpf) module in Comsol (Time dependent and transient with phase initialization) and how to tune the parameters "phi" and "epsilon" for phase initialization? Also, what are the physical meanings of these parameters?
Same problem for the "phase field" method exists.
If anyone can help and share his experience I will be very greatful.

Epsilon is the turbulence parameter which defines the intensity they used for solving turbulent flow problems:RANS
MODELS: the L-VEL, yPlus, Spalart-Allmaras, k-epsilon, k-omega, Low Reynolds number k-epsilon, and SST models
