1、接触对无单元
At least one contact pair has no elements in it.This may be due to mesh defeaturing.Please modify defeaturing settings which are accessible on the Mesh object.Alternatively, set the variable "contactAllowEmpty" to 1 in order to allow the solution to proceed with a warning which can be used to identify the offending pair(s)

解决方法:

 Tools - Variable Manager.

right mouse button click - add

Set Variable :contactAllowEmpty =1

2.查看求解所用单元类型

在ANSYS早期版本中可以通过Component Systems中找到Finite Element Modeler来查看,在Model和Setup模块均可插入,插入后Update Project,即可在Finite Element Modeler中查看所用的单元类型。

但ANSYS高阶版本默认已不能调出Finite Element Modeler,可以通过两种方法查看所用单元类型:

方法一:Tools-Options-Appearance-Unsupported Features,将其勾选,即可重新调出Finite Element Modeler;

方法二:在Solution Information中查看。

3、One or more bodies may be underconstrained and experiencing rigid body motion. Weak springs have been added to attains a solution. Refer to Troubleshooting in the Help System for more details.

此种情况需要查看弱弹簧力,若不超过e-5,可以认为弱弹簧对结果无影响。

不慢不急
