This paper demonstrates how the biological growth method, studied by Mattheck in the 1990s, can be easily implemented for structural shape optimization finite element method (FEM) analyses using advanced radial basis functions (RBF) mesh morphing. We use the same mechanism observed in tree trunks: hot spots of higher stresses promote material growth as well as reducing the stress itself thanks to the added thickness. Mesh morphing is a key enabler in adapting the desired shape, calculated over the surface of the finite element analysis (FEA) mesh, to the entire solid domain. According to the same principle, material can be also removed allowing for lighter structures. We first explain the method by studying a tree trunk and then through a variety of successfully addressed structural optimization challenges.

The Extremely Large Telescope (ELT) is a 40m-class optical and infrared telescope being built in Chile. The ELT has a complex geometry, with a rotating structure and a dome that must be protected from wind effects to ensure accurate observations. To study the wind flow within the dome, a computational fluid dynamics (CFD) model was created.
