SHAPE SENSITIVITY AND OPTIMIZATION FOR TRANSIENT HEAT DIFFUSION-PROBLEMS USING THE BEM
A shape design sensitivity analysis (SDSA) of two-dimensional transient heat diffusion problems is proposed based on the BIE formulation. The adjoint variable method is used by using the Ionescu-Cazimir integral identity. The procedure is checked against the analytical solution in the case of a rod example, and by numerical comparisons with the finite differencing for a rectangular block under thermal shock and a plunger model. An optimal design problem is then formulated for the plunger and solved to obtain a realistic shape.
