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.

void oofem::FluidStructureProblem::solveYourselfAt ( TimeStep * tStep )

virtual

Solves problem for given time step.

Should assemble characteristic matrices and vectors if necessary and solve problem using appropriate numerical method. After finishing solution, this->updateYourself function for updating solution state and then this->terminate function (for updating nodal and element values) should be called.
