Eigenfrequency Analysis of a Free Cylinder

Application ID: 271


This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry.

The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report.

Three different physics interfaces are used: Solid Mechanics and Shell in 2D axisymmetry, and Solid Mechanics in 3D with cyclic symmetry boundary conditions.

In addition to the actual benchmark, it is shown how to also compute eigenmodes with a twisting deformation.
