Displacement (vector), and director vector position, for the inverse finite element (IFEM) results of the reference blade, and optimized blades (Note that the displacement is the manufacturing shape of the web). Vf defines the material volume ratio between the optimized material volume and the original material volume in the web. This file in in ParaView "vtu" format. In all cases, the residue norm was 1e-6. For the reference model with Vf = 100%, the solution was computed in twelve iterations along two load steps. For Vf = 60%, the solution was computed in twenty four iterations along six load steps. The Vf = 50% model required twenty six iterations along six load steps. Finally, Vf = 45 required twenty eight iterations along six load steps. In all cases, the IFEM feasibility tests have succeeded, ensuring that the manufacturing shape of the blade will recover the aerodynamic optimal configuration under the service loads and that buckling is not encountered during deformation.本数据集包含参考叶片与优化叶片的逆有限元（Inverse Finite Element, IFEM）结果中的位移（矢量）与位置方向矢量。（注：此处位移指腹板的制造形状）。Vf定义为腹板内优化后材料体积与原始材料体积的比值。本文件采用ParaView的"vtu"格式存储。所有算例的残差范数均为1e-6。其中，Vf=100%的参考模型历经2个载荷步、共计12次迭代完成求解；Vf=60%的模型历经6个载荷步、共计24次迭代完成求解；Vf=50%的模型历经6个载荷步、共计26次迭代完成求解；Vf=45%的模型最后完成求解，历经6个载荷步、共计28次迭代。所有算例的逆有限元可行性测试均已通过，可确保叶片的制造形状在服役载荷下可复现气动最优构型，且变形过程中不会发生屈曲失稳。
