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.

Hi Zabee,

In explicit dynamics analyses, such as the drop test you performed, stress waves travel through the model upon impact and may interact and amplify each other. This explains why acceleration is locally high at the element level where such interactions occur.
