請問老師們，我在abaqus定義復合材料方向完后，開始計算時提示這樣的錯誤“The user defined normal of the material orientation of 4 elements, as defined in *ORIENTATION, is orthogonal to the GASKET, COHESIVE, SHELL or MEMBRANE normal direction. Check input data. The elements have been identified in element set ErrElemUserNormMatOrient“，是什么問題啊，要怎么解決？
