在松耦合气动弹性计算中，气动模型和弹性力学模型基于不同的网格，最终考虑简化的结构模型，如壳或杆。CFD工具应用于气动网格，而CSM工具应用于结构网格。网格通常是非协调的；因此，为了将结构变形传递到气动表面网格，并将气动载荷传递到结构，需要进行三维和非侵入式的插补。为此，研制了一种基于径向基函数的插补器。该工具不需要网格连通性，可以应用于任何三维数据。
In loosely‐coupled aeroelastic computation, the aerodynamic and elastomechanical models are based on different grids and eventually a simplified structural model, like a shell or stick, is considered. CFD tools are applied over the aerodynamic grid, whereas CSM tools are over the structural one. The meshes are usually non‐conforming; thus, three‐dimensional and non‐intrusive interpolation procedures are necessary to transfer structural deformations to the aerodynamic surface grid and aerodynamic loads to the structure. For that purpose, an interpolator based on radial basis functions has been developed. This tool does not require grid connectivities and can be applied to any three‐dimensional data.
