abaqus合并面線的案例
Abaqus 利用FindAt函數根據坐標查找點，線，面
在ANSYS中可以通過坐標來選取對象，Abaqus雖說沒有ANSYS那么方便，但是也還是可以實現的，主要是通過findAt函數，可以選擇cell（體）、face（面）、edge（邊）和vertex（頂點）。
findAt(): This method returns the object or objects in the VertexArray located at the given coordinates.
findAt initially uses the ACIS tolerance of 1E-6. As a result, findAt returns any Vertex object that is at the arbitrary point specified or at a distance of less than 1E-6 from the arbitrary point. If nothing is found, findAt uses the tolerance for imprecise geometry (applicable only for imprecise geometric entities).
findAt will always try to find objects among all the vertices in the part or assembly instance and will not restrict itself to a subset even if the VertexArray represents such subset.
