1、几何清理

清除不必要的细小特征：孔倒角

调用多个ＣＰＵ

2、由点确定矢量方向

3 RROR # 2502

A fatal error has been detected during input processing:

*** ERROR # 2502 ***

Element 549700 had incorrect node numbering sequence and needs renumbering. ***** ERROR ENCOUNTERED BEFORE COMPLETING THE CHECK RUN *****

(1) 一般发生在修改网格之后，再删除原来的网格的时候没有将element549700删掉，使得该单元上的节点与后来划分的网格的节点出现矛盾冲突；先利用find id=549700删掉该单元

Save found -----F5-mask------retrieve(选择保存的)------reverse(反选)------mask----只显示549700单元了

4 *** ERROR # 1237 ***

CHEXA element number 26323 references a missing property ID 23 or uses property of incorrect type for this element type. （1）由于property ID 23（23号属性定义有问题），没有定义一个正确的单元类型；

（2） 这个地方容易没有填，注意注意

（3）网格划分的质量也有可能出现这个问题，重新划分网格可以消除该错误。（网格画小）

5*** ERROR # 2203 ***

Error(s) encountered during element check

***** Element Quality Check Failed - error limits violation *****

NOTE : To bypass element quality checks (except essential validity checks) use PARAM,CHECKEL,NO. This may, however, cause very poor results. （1）单元质量不好

6 *** ERROR # 312 ***

In static load case 1

the compliance is negative or large 1.875471E+13 Optimization/buckling analysis cannot be performed due to possible rigid body mode

FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED). (1)弹簧没建好；网格划分的不好节点不重合
