Claim:
1. A computer implemented method to simulate aerodynamics over an aircraft for a deflected position of a movable aircraft control surface using a structured chimera mesh, comprising: creating, by an aerodynamics simulation tool residing in a memory, a mesh assembly of the aircraft by overlapping a background mesh and a structured chimera mesh for the deflected position of the movable aircraft control surface; analyzing, by the aerodynamics simulation tool, mesh cell sizes within overlapping boundaries of the background mesh and the structured chimera mesh, wherein analyzing the mesh cell sizes comprises: regenerating, by the aerodynamics simulation tool, the structured chimera mesh for the deflected position of the movable aircraft control surface when the ratio of the mesh cell sizes exceeds the predetermined threshold ratio; reforming, by the aerodynamics simulation tool, the mesh assembly of the aircraft based on the regenerated structured chimera mesh; creating, by the aerodynamics simulation tool, a masked mesh of the aircraft by auto masking the reformed mesh assembly using a patch assembly method; and simulating, by the aerodynamics simulation tool, aerodynamics over the aircraft for the deflected position of the movable aircraft control surface using the masked mesh.
