    Internal and External Coupling Approaches for Fluid-Structure Interaction Problems in SU2


    In this talk two possibilities to handle Fluid-Structure Interaction(FSI) calculations under the usage of SU2 will be presented. For the first one, as given in [1], the coupling of the equations for fluid and structure is done within SU2. The coupled system is then solved by Block-Gauss-Seidel Iterations on its adjoint variables. The second approach is to couple the SU2 framework as solver for the fluid part of the problem with an external structure solver as discussed in [2].
