An extension of shape sensitivity analysis to an immersed boundary method based on Cartesian grids

[EN] Gradient-based shape optimization processes of mechanical components require the gradients (sensitivity) of the magnitudes of interest to be calculated with sufficient accuracy. The aim of this study was to develop algorithms for the calculation of shape sensitivities considering geometric repr...
