  - OS-V: 0400 Pin-ended Double Cross
    Test No. FV2 A pin-ended double cross, in-plane vibration problem. OptiStruct is used to investigate the coupling between flexural and extensional behavior, as well as the repeated and closed eigenvalues of the double cross in Normal Modes Analysis.
  - OS-V: 0410 Cantilever with Off-Center Point Masses
    Test No. FV4 This problem tests the behavior of coupling between torsional and flexural, off-center inertial axis, and close eigenvalues. OptiStruct is used in this normal modes analysis.
  - OS-V: 0415 Deep Simply-Supported Beam
    Test No. FV5 OptiStruct tests the repeated eigenvalues, shear deformation, and rotary inertia. The possibility of missing extensional modes is also investigated.
  - OS-V: 0420 Free Thin Square Plate
    Test No. FV12 A thin square plate model that contains three rigid body modes. OptiStruct investigates the repeated eigenvalues and kinematically incomplete suppressions of the thin plate in Normal Modes Analysis.
  - OS-V: 0425 Clamped Thin Rhombic Plate
    Test No. FV15 The behavior of distorted thin elements in normal modes analysis is examined using OptiStruct.
  - OS-V: 0430 Cantilevered Thin Square Plate
    Test No. FV16 A cantilevered thin square plate of 10 m × 10 m dimension. OptiStruct is used to investigate the frequencies at different modes for different test cases.

  - OS-V: 0450 Free Cylinder: Axisymmetric Vibration
    Test No. FV41 A free cylinder with axisymmetric vibration. OptiStruct is used to investigate the rigid body mode, close eigenvalues, and the coupling between axial, radial and circumferential behavior.
  - OS-V: 0455 Simply-Supported Solid Square Plate
    Test No. FV52 A well-established solid square plate, which contains three rigid modes with the given boundary condition. The test examines the performance of OptiStruct Normal Modes Analysis on 3D solid elements.
