The Wall Distance Initialization () study step is added to the Stationary with Initialization and the Time Dependent with Initialization studies when using a turbulent model. This first step is dedicated to solving for the reciprocal wall distance. For turbulence models, the distance determined in the initialization step is the distance to the closest wall. For two-phase flow it is the distance to the phase interface. The settings for this study are the same as for the Stationary and Time Dependent studies.
