離散剛體在hypermesh畫網格導入ABAQUS運算出現錯誤?
(1)我模擬的是一個三通管的漲形實驗,原先在abaqus中畫網格,但是由于我在ABAQUS中沒能將網格畫的很好,所以我將離散剛體殼體模具拿到hypermesh中去畫。然后再以.inp文件的形式倒回到ABAQUS中,其他設置都沒有變,但是在仿真的時候提示我出問題了。我看了下主要是提示我那個模具上的參考點出問題了。

(2)這是我在hypermesh導出的離散剛體模具,在ABAQUS中加了一個參考點,結果出錯了,主要錯誤為下面的提示。

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained. Either mass must be defined or all of the translational degrees of freedom must be constrained. See the status file for further details.
The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRot1Axis have atleast one axis about which the rotary inertia magnitude is zero, and the rigid bodies have atleast one rotational degree of freedom which is unconstrained. Either rotary inertia must be defined at the reference nodes or all of the rotational degrees of freedom at the reference nodes must be constrained. See the status file for further details.
Abaqus/Explicit Packager exited with an error - Please see the status file for possible error messages if the file exists.
(3)疑問?
是不是只有網格信息的模具,和原先具有幾何信息的模具他們的設置有所不同呢,為啥會提示缺少質量和有自由度沒有約束呢,看結果文件好像都指向這個網格模具的參考點。
(4)對這個模具的所有操作如下:
首先將這個模具導入后我將其設置為離散剛體,將這個怕Part復制到原先的Model中,刪除帶入的這個模型文件;然后在interaction這一步中定義了模具的內表面,定義了其與內部管件的相互接觸關系;在mesh模塊中定義了單元類型。然后提交分析,最后出錯而結束分析了。
