7. Conclusions

In this paper an original solver for FSI problems has been presented; this solver has been implemented in Open FOAM, an opensource software developed for Linux distributions and released under a GPL license with the C ++ source code. This solver, modsFsiFoam , allows to reach the fluid-dynamic solution through the Finite Volume Method. Considering the bad results obtained through FSI solvers based on the FVM for both computational fields, it has been
