Finite element modeling of wind forces on trees

Singapore's National Parks is partnering with university-based researchers to apply Finite Element Modeling techniques to better understand the dynamic behavior of trees during wind gusts. A Finite Element Model breaks down a complex structure into smaller components with simpler geometry and aggregates the response of each component to external forces to simulate the behavior of the larger structure. In this case, trees can be deconstructed into smaller constituent parts such as leaves and branches. Initial findings reveal that "the oscillation of branches and leaves during strong wind can help to dissipate a significant amount of wind energy from being transmitted to the trunk of the tree." These insights inform pruning schedules and techniques to better balance aesthetic, horticultural, public safety, and resilience concerns.

This points towards a future where trees sit alongside buildings in urban digital twins as computational objects of extreme complexity and nuance, revealing tremendous resilient and elevating their perceived value.
