turbulent_wall_libb Subroutine

public subroutine turbulent_wall_libb(me, state, bcBuffer, globBC, levelDesc, tree, nSize, iLevel, sim_time, neigh, layout, fieldProp, varPos, nScalars, varSys, derVarPos, physics, iField, mixture)

BC routine for turbulent wall. It uses wall model to compute velocity on the boundary node. The implementation is based on the following paper: Haussmann, Marc; Ries, Florian; Jeppener-Haltenhoff, Jonathan B.; Li, Yongxiang; Schmidt, Marius; Welch, Cooper et al. (2020): Evaluation of a Near-Wall-Modeled Large Eddy Lattice Boltzmann Method for the Analysis of Complex Flows Relevant to IC Engines. In Computation 8 (2), p. 43. DOI: 10.3390/computation8020043.


```lua boundary_condition = { { label = 'wall', kind = 'turbulent_wall', curved = true, wall_model = 'musker', nonlinear_solver = 'fixed_point' } }

This subroutine's interface must match the abstract interface definition boundaryRoutine in bc/mus_bc_header_module.f90 in order to be callable via fnct function pointer.
