This example is taken from Cornell University’s ANSYS AIM Learning Modules

Problem Specification

Consider an aluminium beam that is clamped at one end, with the following dimensions.

The aluminium used for the beam has the following material properties.

Using ANSYS Discovery AIM find the first six natural frequencies of the beam and the mode shapes.

Geometry

In this video, you will learn to create a cantilever beam for the modal analysis according to the dimensions specified.

Mesh

In this example, we will be using Automatic Physics-Aware Meshing. Automatic physics-aware meshing helps automate and simplify your problem setup. With automatic physics-aware meshing, the computational mesh is generated automatically based on the solution fidelity setting and the physics inputs.

Physics Setup

In this video, you will learn to assign material and modify it according to the problem specification and also assign boundary conditions for the cantilever beam.

Results

In this video, you will see how to extract the frequencies for all the modes and also determine the mode shape and contours.
