Abstract
Fluid Structure Interaction (FSI) is widely applied in aircraft aerodynamic and aeroelastic analysis. Iteration between the CFD and FEA will solve the aerodynamic force, flow field, structure stress and deformation under equilibrium state simultaneously. In aircraft product development, the CFD mesh and Finite element model normally do not match each other because the goal of CFD and FEA are different. To connect between unmatched interface, a pixelation method is developed to transfer the aerodynamic loads onto the finite element model correctly. The pixelation method is also easy to be implemented and parallelized.
