A small insect not only run on water, but also jump because of the large surface tension.
Keywords: Meniscus wall breaking, Surface tension, Legged jump
Openfoam, VOF, Static contact angle of 167deg
On-water jump simulation by FSI:
This case broke the Meniscus wall and could not jump higher.
On-water Landing Experiments: 4-leg model, specific gravity of 7.9, fall height of 50mm, pitch angles of 30deg and 45deg, leg lengths of 7.5mm and 15mm.
Short leg and small angle: The leg did not break the meniscus wall
Short leg and large angle: The leg broke the meniscus wall
Long leg and large angle: one leg broke the meniscus wall but the others
