“For node list paths, the node labels that constitute the path are equally applicable to undeformed and deformed model shapes. However, point list path coordinates remain fixed in space and are independent of your model. For example, coordinates that coincide with a nodal location on the undeformed shape may not coincide with any location on the deformed shape. Values obtained using point list path coordinates and the deformed model are affected by the deformation scale factor. Abaqus does not form data pairs for points that do not coincide with your model.”這是abaqus幫助文檔里面的一段話，大概意思就是說選擇單元節(jié)點生成路徑的話，因為節(jié)點是固定的，不管變形與否，abaqus就可以生成圖像，因為單元節(jié)點一直都在模型上，隨著模型的變形而改變。但是選擇點的話，因為abaqus記錄的是點的空間坐標(biāo)，變形后的點的坐標(biāo)就變了，這時你選擇的點不在你的模型上，abaqus就不能生成圖像。因為你選擇的是點，而不是節(jié)點，所以才會提示你說的那個。在這里我覺得直接選擇“未變形（undeformed）”就可以生成圖像了，當(dāng)然，你定義的路徑也必須是在“未變形（undeformed）”的狀態(tài)下的模型上定義的。要想生成變形后的數(shù)據(jù)圖像，只能選擇定義節(jié)點路徑。詳細(xì)的可以去看看abaqus documentation。這是我的理解。如有錯，請指教。
