Adjoint shape design sensitivity analysis of fluidsolid interactions using concurrent mesh velocity in ALE formulation
Accurate adjoint shape design sensitivity for coupled FSI problems. Efficient shape sensitivity analysis using converged tangent from nonlinear FSI analysis. Variational equation includes the moving boundary of fluids in ALE formulation. Concurrent mesh velocity determined from a displacement-loaded pseudo-structural problem. A fast convergence of total solution due to consistent fluid mesh, interface, and solid mesh.
