Abstract
A system and method for simulating aerodynamics over an aircraft for a deflected position of a movable aircraft control surface using a structured chimera mesh are disclosed. In one embodiment, a mesh assembly of the aircraft is created by overlapping a background mesh and a structured chimera mesh for the deflected position of the movable aircraft control surface. Further, mesh cell sizes within overlapping boundaries of the background mesh and the structured chimera mesh are analyzed. Furthermore, the structured chimera mesh is regenerated based on the analysis. In addition, the mesh assembly of the aircraft is reformed based on the regenerated structured chimera mesh. Also, a masked mesh of the aircraft is created by auto masking the reformed mesh assembly. Moreover, aerodynamics is simulated over the aircraft for the deflected position of the movable aircraft control surface using the masked mesh.
