Linkwise Dirichlet potential non-equilibrium boundary condition for curved and straight walls. For straight wall, physical boundary overlaps with boundary node i.e. qVal=0.0.
The pdf is decomposed into equilibrium (eq) and non-equilibrium (neq) part: f = f_eq(x_b,t) + f_neq(x_f,t)
Usage
boundary_condition = {
{ label = 'inner',
kind = 'potential_noneq_expol',
potential = pot_inner,
}
}
For straight boundaries, qVal=1.0: Luo, K., Wu, J., Yi, H., & Tan, H. (2016). Lattice Boltzmann model for Coulomb-driven flows in dielectric liquids dielectric liquids. Physical Review E, 23309(93), 1–11. http://doi.org/10.1103/PhysRevE.93.023309
This subroutine's interface must match the abstract interface definition boundaryRoutine in bc/mus_bc_header_module.f90 in order to be callable via boundary_type function pointer.
