TURB is a struct with fields, turb.model indicating turbulence model (kEpsilon, realizableKE RNGkEpsilon, kOmega, kOmegaSST, or SpalartAllmaras), turb.inlet a vector with two components specifying the inlet values k/epsilon or k/omega when using the corresponding models (can also be computed using the turbulence_inletbccalc function), and turb.wallfcn is a logical flag designating if turbulent wall functions should be used.

INIT by default takes the initial value expressions from the physics modes. It can also be overridden to select a previous solution (integer init = i specifies the solution number), or use potentialFoam to compute the initial values (init = -1).
