为什么我用workbench将fluent得到的数据与模型进行耦合出现Mechanical Mapped Forces-技术邻

Question

为什么我用workbench将fluent得到的数据与模型进行耦合出现Mechanical Mapped Forces for Mechanical Surface 和CFD Computed Forces from CFD Results的力完全不一样，而且方向还是不同的，谁能帮帮忙啊

<br/>可以的

我选择的时候确实是选择完全相同的面，只不过我的模型不是在ansys workbench中的DM直接建模的而是通过proe建模，并且转化为第三方格式才导入的，这样不知道行不行

CFD Computed Forces from CFD Results File C:\Users\cindy\AppData\Local\Temp\WB_CINDY-PC_4588_2\unsaved_project_files\dp0\SYS\MECH\Solution 1\zz-zjm-1357bu-2-00071.dat.gz
X-component = 155.28 N
Y-component = 34.769 N
Z-component = -182.87 N
Mechanical Mapped Forces for Mechanical Surface File C:\Users\cindy\AppData\Local\Temp\WB_CINDY-PC_4588_2\unsaved_project_files\dp0\SYS\MECH\Import_ANSYS_386.cdb
X-component = -1026.2 N
Y-component = -1006.2 N
Z-component = -319.27 N
16% of Mechanical nodes were mapped to the CFD surface, remaining nodes mapped to closest edge or node.
为什么会出现这种情况
