Abstract :
A study of various sampling strategies for extracting reduced models from moderate dimension parametric spaces of finite element (FE) models is conducted. Tensor-product, Monte Carlo method and its various quasi-Monte Carlo alternatives (Sobol, Halton) and sparse grid sampling strategies are compared for a doubly infinite antenna array example.
