我在做热分析时选的PLANE55和surf151单元,但在之后计算热应力时选择thermal to struc,会出现错误提示,Shape testing revealed that 70 of the 71 new or modified elements violate error limits。To review test results,please see the output file or issue the CHECK command,点proceed后又2出现waring:The ETCHG has changed some element types。please examine not only the KEYOPTs,but also the real constants,material properties,boundary conditions and loadings,and then modify as needed.之后再查看单元类型,就变成PLANE182和SURF153了,我该怎么做啊,谢谢好心人的指导,谢谢。 |
