/************************************************************************
File pdh_ns_mixed_bc.h - types and functions related to boundary conditions 
               for Navier-Stokes SUPG approximation
               
Contains definition of types used by bcs               

Contains declarations of routines:
  pdr_ns_mixed_bc_read - read bc data from config file
  pdr_ns_mixed_bc_free - free bc resources
  pdr_ns_mixed_get_bc_count - get num of boundaries with conditions set in file
  pdr_ns_mixed_get_pressure_pins_count
  pdr_ns_mixed_get_velocity_pins_count
  pdr_ns_mixed_get_pressure_pin - get pressure pin data
  pdr_ns_mixed_get_velocity_pin - get velocity pin data
  pdr_ns_mixed_get_bc_type - get type of flow bc for boundary
  pdr_ns_mixed_get_bc_data - get flow bc data
  pdr_ns_mixed_update_timedep_bc - update timedependent boundary conditions
