Kurzfassung
The inclusion of structural deformations into aerodynamic computations is mandatory for nowadays highly accurate computational fluids dynamics (CFD) solvers. These CFDCSM simulations are often performed with beam-stick structural models. This paper gives an overview about the usage of CFD-CSM interaction with very detailed structural models in an R+T context. Application examples are a detailed, but linear, AWIATOR test case FEM as well as multibody and nonlinear structural models for large civil aircrafts. For this kind of examples, the coupling method of aerodynamic and structural model has increased requirements. Additionally for complex aircraft configurations, the stability of CFD-CSM chains is reduced through the possibility of negative cell occurrances in the CFD mesh after deformation. A method using a finite-element method approach is introduced to repair these negative cells at runtime.
