4. B modeling#
4.1. Characteristics of modeling#
The average deformation resulting from a harmonic calculation is calculated.
An excitation frequency equal to \(200\mathrm{Hz}\) is chosen.
The operator OBSERVATION is also used for the surveys of displacement fields and deformation.
4.2. Characteristics of the mesh#
Knots: 1029
Meshes: 720 HEXA8
4.3. Tested sizes and results#
The deformation value is tested at the nodes located at the free end of the beam.
