Dear fellow SU2 users,

I am trying to find more information on the "Engine Simulation" section in the SU2 config template (see code snippet below). Unfortunately, I cannot find any relevant test cases, tutorials or publications on this feature.

I have several questions:
1) What is meant by "MRF"?
2) Can I use the model also for a 2D-axisymmetric cases or just for a full or half model of the engine?
3) If I define ACTDISK_JUMP= RATIO, I assume I can define the total pressure ratio across the "engine". Where can I define the desired value for the pressure jump?
4) Do you know of any example configuration files, which I can use to base my own simulation setups on?

Thank you for your help!

% -------------------------- ENGINE SIMULATION --------------------------------%
% Highlite area to compute MFR (1 in2 by default)
% Fan polytropic efficiency (1.0 by default)
% Only half engine is in the computational grid (NO, YES)
% Damping factor for the engine inflow.
% Damping factor for the engine exhaust.
% Engine nu factor (SA model).
% Actuator disk jump definition using ratio or difference (DIFFERENCE, RATIO)
% Number of times BC Thrust is updated in a fix Net Thrust problem (5 by default)
% Initial BC Thrust guess for POWER or D-T driver (4000.0 lbf by default)
% Initialization with a subsonic flow around the engine.
% Axis of the cylinder that defines the subsonic region (A_X, A_Y, A_Z, B_X, B_Y, B_Z, Radius)
SUBSONIC_ENGINE_CYL= ( 0.0, 0.0, 0.0, 1.0, 0.0 , 0.0, 1.0 )
% Flow variables that define the subsonic region (Mach, Alpha, Beta, Pressure, Temperature)
SUBSONIC_ENGINE_VALUES= ( 0.4, 0.0, 0.0, 2116.216, 518.67 )
