N2 - This paper presents an advancement of a model-independent surrogate based optimization method with adaptive sampling, known as Adaptive Model Refinement. The primary advancement relates to the capability to identify optimum location to add new samples. To this end, a new variable fidelity optimization method is proposed, where the timing of refinement and the number of infill points are determined based on the existing work in adaptive model refinement, and the location of the infill points are uniquely decided by integrating a GP-based criteria (“q-EI”) adopted from Bayesian optimization. Preliminary optimization runs showcase the achievement of up to 9% of drag reduction.
