Abstract:

Sensitivity analysis is important in structural reliability, optimization and system identification applications. The development of sensitivity analysis for fluid-structure interaction (FSI) problems provides an important tool for assessing the reliability and performance of coastal infrastructure. The Particle Finite Element Method (PFEM) is used to solve the FSI problem both in the response as well as for sensitivity analysis using the direct differentiation method (DDM). PFEM sensitivity analysis through the DDM is performed considering fixed mesh solutions for verification purposes as well as for geometric nonlinearity for turbulent flows arising from FSI.
