Detailed Description

Implementation of fluid-structure interaction ) problem based on Dirichlet-Neumann approach. The problem consists in pair of structural (DIIDynamic) and fluid (PFEM) problem.

The FluidStructureProblem provides an iterative synchronization of sub-problems. The convergence criterion is based on the difference of the pressure and velocity values on the interface from the subsequent iterative steps.
