PARAM, AEMESH

Bulk Data Entry Controls output of aerodynamic mesh used in aeroelastic analysis and the displacement field on the aerodynamic mesh.

Parameter Values Description
AEMESH <YES, NO>
YES
The aerodynamic mesh used in aeroelastic analysis and the displacement field on the aerodynamic mesh are both output to H3D.
NO (Default)
Neither the aerodynamic mesh nor its displacement are output to H3D.

Comments

  1. PARAM, AEMESH is applicable to trim, flutter and normal mode analysis and generally used for splining verification purposes.
  2. For normal mode analysis, you can define the aerodynamic mesh using CAERO1/CAERO2 and SPLINE1/SPLINE2 cards in the input deck and PARAM, AEMESH, YES triggers the calculation of spline interpolation matrix internally.
  3. If there is no aeroelastic subcase, normal mode subcase, or aerodynamic element defined in the input deck, PARAM, AEMESH, YES is ignored.
  4. For divergence analysis, PARAM, AEMESH, YES only outputs the aerodynamic mesh to H3D without any eigenvector displacement applied on it.
  5. For flutter analysis, PARAM, AEMESH, YES does not output the displacement of the complex eigenvectors obtained from the flutter eigenvalue equation. Instead, it only outputs the displacement of the normal modes when the user request DISPLACEMENT(MODAL).
  6. Currently, partial output of the displacement field of the aerodynamic mesh is not supported. Namely, once PARAM, AEMESH is turned on, the displacement values at all aerodynamic mesh grids are output.
