Maintaining surface area: Making a flag

[wim (Wim Dekeyser)]

Hi Ernst -
You could also look into simulating it with Kangaroo in Grasshopper:

Kangaroo Wind Control

Hi @zic_23 The flapping of a flag in the wind is not primarily driven by variations in the wind velocity - even in a perfectly steady wind, it will still flap, and that’s what’s happening in the simulation. What happens is a feedback loop - depending on their angle, some parts of the mesh catch more of the wind, so parts of the mesh move differently. The tension of the fabric makes all the parts interact, and it gets pulled into a new shape, which results in a new wind force distribution, and …
