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:
http://www.arc.umn.edu/ http://www.mems.rice.edu/TAFSM/PROJ/FSI/axi_para.html http://www-sscom.army.mil/warrior/98/oct/airdrop.htm "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." |
