On these pages results of simultaneous fluid / structure calculations on coupled problems are presented.

Although the governing equations and computational methods for either the solid or the fluid domain are sophisticated and well developed, treatment of the physics of the coupled or whole system together with the moving boundaries remains a demanding problem.

In UNSI a flexible membrane airfoil (sail) was chosen as a testcase [1].

• 1) 2D Flexible Membrane Airfoil (Sail)

• 2) Flow induced oscillations af a rectangular bluff body
