Vortex Model Test
This animation shows a tornado vortex model coupled with a tree stability model merged with infrastructure
fragility simulations. The images show standing trees (green dots), treefall vectors
(red arrows), buildings (gray hatched polygons) and building roof panels (triangles) originating from the
crosses on the buildings with the corresponding colors. The background colors show the wind speed (in
m s-1) and wind vectors (small black arrows).
