Default Elastic membranes (such as sails) under aerodynamic loading

Dear all,

Is anyone working on *structured* grid methods for the interaction between (air)flows and elastic membranes, such as sails? If so, I'd like to share experiences.

Thanks, Margot Gerritsen

A problem similar to sails is parachute membrane fluid-structure interaction (FSI) -- see:

"All airdrop systems encounter highly complex fluid structure interaction (FSI) phenomena as they deploy, inflate, reach steady state conditions, and ultimately provide a soft landing. Without an accurate representation of the inflated parachute shape, the FSI phenomena make it impossible to predict accurately the pressure distribution on a canopy surface. At the same time, the parachute's shape cannot be determined without an accurate representation of the pressure distribution (and other loadings) acting over its surface."
