Research about Influencing Factor on Interpolation Accuracy in Data Exchange of Fluid-Structure Interaction
Six kinds of interpolation methods, including projection-shape function method, three-dimensional linear interpolation method, optimal interpolation method, constant volume transformation method and so on, were adoped in the study of interpolation accuracy.From the point of view about the characterization of matching condition of two different grids and interpolation function, the infuencing factor on the interpolation accuracy was studied.The results revealed that different interpolation methods had different interpolation accuracy.The projection-shape function interpolation method had the best effect and the more complex interpolation function had lower accuracy.In many cases, the matching condition of two grids had much greater impact on the interpolation accuracy than the method itself.The error of interpolation method is inevitable, but the error caused by the grid quality could be reduced through efforts.
