FULGURITES SIMULATION - STRUCTURE FORMATION

In this step, the main focus of the simulation is how to grow sand particles from the initial path—using the DLA algorithm with specific settings to reproduce the part of the particles, growing from the starting pathway to the outward direction, creating the roughness shape of fulgurites body. Controlling of alignment of particles and noise scale settings can simulate the roughness and bumping skin of the fulgurites simulation, in reality, which is the skin of fulgurite’s outer shell.

PARTICLES AGGREGATION

The initial area in these simulations is a linear and circular shape—the growing particles created the roughness of the skin and the thickness of the structure.

FULGURITES SIMULATION - STRUCTURE FORMATION

The structure formation and particle aggregation are combined in the final simulation. In each second, the structure grows from the top to the bottom direction, and the particles grow following the structure path.

FULGURITES SIMULATION - 3D PRINTING

After the DLA simulations the thickness, length, number of branches and direction of the structures are able to be controlled. The results of the simulations were 3d-printed for the physical expertise.
