Query: Fluid structure system with boundary conditions involving the pressure   We study a coupled fluid-structure system involving boundary conditions on
the pressure. The fluid is described by the incompressible Navier--Stokes
equations in a 2D rectangular type domain where the upper part of the domain is
described by a damped Euler--Bernoulli beam equation. Existence and uniqueness
of local strong solutions without assumptions of smallness on the initial data
is proved.
