We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Use the word Vertex when referring to the 3-2-1 method. Applying constraints to edges would not be a valid 3-2-1 method.
Using Rigid Elements on the edges of the section prevents the Poisson's Ratio expansion when the compression is applied, which generates a stress along the web and flange edges.
Use the Deformable type of Rigid Elements to fix this.
