MSES Analysis Interface Module (AIM)
AIM Inputs

The following list outlines the MSES inputs along with their default values available through the AIM interface.

  • Mach = NULL
    Mach number.
  • Re = 0.0
    Reynolds number. Use 0.0 for an inviscid calculation.
  • Alpha = NULL
    Angle of attack [degree].
  • CL = NULL
    Prescribed coefficient of lift.
  • Acrit = 9.0
    Critical amplification factor "n" for the e^n envelope transition model. 9.0 is the standard model.
  • xTransition_Upper = NULL
    List of forced transition location on the upper surface of each blade element. Must be equal in length to the number of blade elements.
  • xTransition_Lower = NULL
    List of forced transition location on the lower surface of each blade element.
    Must be equal in length to the number of blade elements.
  • Mcrit = 0.98
    "critical" Mach number above which artifical dissipation is added.
    0.99 usually for weak shocks
    0.90 for exceptionally strong shocks
  • MuCon = 1.0
    artificial dissipation coefficient (1.0 works well),
    (A negative value disables the 2nd-order dissipation.
    This is a “last-resort” option for difficult cases.)
  • ISMOM = 4
    MSES ISMOM input to select the momentum equation. Valid inputs: [1-4]
    1 -> use S-momentum equation
    2 -> use isentropic condition
    3 -> use S-momentum equation, with isentropic condition only near leading edge
    4 -> use isentropic condition, with S-momentum equation only where dissipation is active
  • IFFBC = 2
    MSES IFFBC input to select the Farfield BC. Valid inputs: [1-5]
  • Coarse_Iteration = 200
    Maximum number of coarse mesh iterations (can help convergence).
  • Fine_Iteration = 200
    Maximum number of fine mesh iterations.
  • GridAlpha = 0.0
    Angle of attack used to generate the grid.
  • Airfoil_Points = 201
    Number of airfoil grid points created with mset
  • Inlet_Points = NULL
    Inlet points on leftmost airfoil streamline created with mset
    If NULL, set to ~Airfoil_Points/4
  • Outlet_Points = NULL
    Outlet points on rightmost airfoil streamline created with mset
    If NULL, set to ~Airfoil_Points/4
  • Upper_Stremlines = NULL
    Number of streamlines in top of domain created with mset
    If NULL, set to ~Airfoil_Points/8
  • Upper_Stremlines = NULL
    Number of streamlines in bottom of domain created with mset
    If NULL, set to ~Airfoil_Points/8
  • xGridRange = [-1.75, 2.75]
    x-min and x-max values for the grid domain size.
  • xGridRange = [-2.5, 2.5]
    x-min and x-max values for the grid domain size.
  • Design_Variable = NULL
    The design variable tuple is used to input design variable information for the model optimization, see cfdDesignVariable for additional details. Must be NULL of Cheby_Modes is not NULL.
  • Cheby_Modes = NULL
    List of Chebyshev shape mode values for shape optimization (must be even length with max length 40). Must be NULL if Design_Variable is not NULL
