fluid_pnpn_setup_bcs()

subroutine fluid_pnpn::fluid_pnpn_setup_bcs ( class(fluid_pnpn_t), intent(inout), target  this, type(user_t), intent(in), target  user, type(json_file), intent(inout)  params  )

private

Each entry of case.fluid.boundary_conditions is split into a velocity part and a pressure part by fluid_pnpn_bc_split. The parts are passed to velocity_bc_factory and pressure_bc_factory, and the resulting objects are appended to bcs_vel and bcs_prs and marked in the residual projectors. The facet_type array of the mesh, used by the FDM preconditioner, is set to 1 on the zones of an entry with a Dirichlet pressure condition and to 2 otherwise.

Parameters

user	The user interface.
params	The case file parameters.

private

Parameters

t	The time value.
tstep	The current interation.
dt	The timestep
ext_bdf	Time integration logic.
dt_controller	timestep controller
