Abstract

Abstract

In the process of fluid-structure coupling analysis, it is necessary to use appropriate data transfer method to map the node load onto the structural grid. To meet the accuracy requirements of nodal force transfer on complex surfaces, a search algorithm based on the critical dihedral angle criterion and the maximum/minimum influence radius was proposed to determine the interpolation area on the surface. A 3D node force interpolation method based on the principle of minimum potential energy was used to transfer node force data between 2 sets of calculation grids, the consistency of load distributions, resultant forces, and resultant moments after transfer was verified through numerical examples.
