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。
