Dear friends, could anyone kindly show me how to set the Nacelle's boundary condition，such as the fan inlet ,fan out let and core outlet? I have tried to set as below, but the result always divergence.
% Engine Inflow boundary type (FAN_FACE_MACH, FAN_FACE_PRESSURE, FAN_FACE_MDOT)
ENGINE_INFLOW_TYPE= FAN_FACE_MACH
%
% Engine inflow boundary marker(s) (NONE = no marker)
% Format: (engine inflow marker, fan face Mach, ... )
MARKER_ENGINE_INFLOW= ( fan inlet, fan face Mach)
%
% Engine exhaust boundary marker(s) with the following formats (NONE = no marker)
% Format: (engine exhaust marker, total nozzle temp, total nozzle pressure, ... )
MARKER_ENGINE_EXHAUST= ( fan outlet, total fan outlet temp, total fan outlet pressure, core outlet, total core temp, total core pressure)

I found in the option structure as below:
/*!
* \brief types engine inflow boundary treatments
*/
enum ENGINE_INFLOW_TYPE {
FAN_FACE_MACH = 1, /*!< \brief User specifies fan face mach number. */
FAN_FACE_MDOT = 2, /*!< \brief User specifies Static pressure. */
FAN_FACE_PRESSURE = 3 /*!< \brief User specifies Static pressure. */
******************************
For Face Mdot, is the brief right?
