HIRENASD FEM wing only HEX20

The finite element model being used by the AePW is based on the model provided at HIRENASD website

The NASTRAN FEM's using HEXA solid elements and identified as "structured"(str) is the one that will be used. Another exists which uses TETRA elements and is labeled "unstructured"(unstr). The original FEM's as provided on the website had different coordinate systems and are in different units.

  • str = mm
  • unstructured = meters The coordinate systems for each of the FEM are different also. To facilitate use both FEM's were modified so that the x direction is in the flow direction, y - is out the wing and z is goes from lower surface to upper surface of the wing and the models are in meters. Mode shapes and frequencies were calculated with both FEM's and a frequency comparison is provided. The only model NASA has used is the "str" model. Comparisons of the FEM as provided from HIRENASD website with as modified are provided
