本文记录 ANSYS Workbench 在使用过程中的 Warning 以及警告的原因，具体内容来自ANSYS的帮助文档（检索功能有待加强）
- Large deformation effects are active which may have invalidated some of your applied supports such as displacement, cylindrical, frictionless, or compression only. Refer to Troubleshooting in the Help System for more details.
结构在大变形迭代更新过程中，原本通过坐标系施加的边界条件（如Ux=0，法向固支），若变形后边界发生了转动，继续根据Ux=0不能再保持法线方向，因此需要根据新的法线方向施加边界条件。
官方：In a large deformation analysis, the program updates the nodal coordinates as the solution progresses towards the final configuration. As a result, supports that fix only some of the degrees of freedom of a node but not all (for example fix only UX=0), may become invalid as the model's nodal coordinates and thus nodal rotation angles are updated. The imposed DOF displacement directions do not change even though rotation angles change. This may or may not be a desirable situation. A classic example is a simple torsion of a rod. Initially the nodes at zero degrees have a circumferential direction of UY but after a twist of 90 degrees, have a circumferential direction of UX.
