MKAERO2 M1 K1 M2 K2 M3 K3 M4 K4


In this example, 3 (Mi, Kj) pairs will be used for calculation of the aerodynamic matrix.

MKAERO2 0.3 0.010 0.69 0.033 0.69 0.1


Field Contents SI Unit Example
Mi Value of Mach number.

No default (Real ≥ 0.0)

Kj Value of reduced frequency.

No default (Real > 0.0)



  1. Aerodynamic matrices will be computed only using the defined set of Mach number and reduced frequency pairs (Mi, Kj). This is different from MKAERO1, where the aerodynamic matrices will be computed using all combinations of (Mi, Kj) pairs from the table.
  2. If embedded blanks are present in any of the pairs, the pair will be skipped.
  3. In case of MKAERO2, continuation line is not allowed. This is different from MKAERO1 where the continuation line is allowed.
  4. Multiple MKAERO2 entries are allowed.
  5. This entry is supported only with Flutter Analysis
