spc_outlet_expol Subroutine

  1. mus_bc_species_module.f90
  2. mus_bc_species_module
  3. spc_outlet_expol

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

species Outlet Pressure extrapolation boundary. NOT VERIFIED

This is taken from the paper: M. Junk and Z. Yang, Asymptotic Analysis of Lattice Boltzmann Outflow Treatments Commun. Comput. Phys., pp. 1–11, 2011.

  • Pressure as defined in the configuration file Usage
boundary_condition = {
 { label = 'outlet',
    kind = 'spc_outlet_expol',
    pressure = 'p1'
  }
}
variable = {
  name = 'p1',
  ncomponents = 1,
  vartype = 'st_fun',
  st_fun = 1.0
}

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.
