- Optimisation of the weight and cost of mechanical components has mostly been performed using finite element methods. But this presents difficulties, e.g. with stepped boundaries that retard convergence, particularly when optimising the structural topology. We show how, instead, an implicit description of geometry in a boundary element context provides a smooth evolution of design geometry in topology optimisation, resulting in the scheme converging in 198 iterations to an optimum compared to 1500 and 2021 iterations using previous methods. Oliveira [EABE (2017) 85:116-126] stated it was a “key feature” that represents "an attractive advantage when compared to hard-kill approaches”
