For unstructured grid methods, the entire notion of a sequence of refined meshes simulations were intended to match with experimental data collected with transition The FUN3D,15, 16 second-order accurate, unstructured grid solver was used to Table 2: Computed order property and GCI for the nose landing gear. In this paper, the flow simulation system, HOTNewt, under development at Cambridge Flow Solution Ltd3, is described with the aim of performing fast and accurate simulations for cases like landing gear aeroacoustic analysis using very limited computing resource. This paper describes the following solutions for the above challenges: 1).
