# Revisiting density-based topology optimization for fluid-structure-interaction problems

@article{Lundgaard2018RevisitingDT, title={Revisiting density-based topology optimization for fluid-structure-interaction problems}, author={Christian Lundgaard and Joe Alexandersen and Mingdong Zhou and Casper Schousboe Andreasen and Ole Sigmund}, journal={Structural and Multidisciplinary Optimization}, year={2018}, volume={58}, pages={969-995} }

This study revisits the application of density-based topology optimization to fluid-structure-interaction problems. The Navier-Cauchy and Navier-Stokes equations are discretized using the finite element method and solved in a unified formulation. The physical modeling is limited to two dimensions, steady state, the influence of the structural deformations on the fluid flow is assumed negligible, and the structural and fluid properties are assumed constant. The optimization is based on adjoint… Expand
