Hypermesh常见错误和知识集锦

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

7 *** FATAL ERROR # 8111 ***

vfileio:: Failed write for file[0], i/o 16384/0,

name=./dl32_DESIGN_TRUE_3load_parame_2624_00.scr. This is likely caused by insufficient disk space

*** ERROR # 151 ***

Error accessing the scratch files:

error encountered in subroutine \

Solver error no. = -110 index = 1

This may be caused by insufficient disk space or some other system resource related limitations.

(e.g. The Operating System or NFS cannot handle file size > 2 GB.) This error was detected in subroutine prepslv4.

(1)主要原因就是内存不足，将该文件的工作目录下的不必要文件删掉或者是移走释放该硬盘下的文件，释放内存就OK

*** ERROR # 1479 *** 8 *** ERROR # 1000 ***

*** ERROR # 1000 *** in the input data: Incorrect data in field # 3.

This line was interpreted as:

52569:CHEXA, 4341, 0, 5272, 5271, 5275, 5274, 5843, 5846 Expected INT > 0, found INTEGER (0).

Syntax error(s) found in bulk data 'CHEXA' card.

Following error/warning messages appeared too many times and were suppressed: 1000 1494

Total of 9979 repeat error message(s) were suppressed.

To see more messages use \（1）主要原因：component定义的property定义出现问题，可能component没有附上property；可以将显示设置为

，这样看是否有未付属性的区域（显示为灰色）

9 *** ERROR # 23 ***

ID 1 used on Case Control data SPC or SPCADD is missing in bulk data. （1） 主要原因：constraint，或者是load的定义为空，就是没有数值；

解决方法：将其他的collector隐藏，只显示load collector，查找到未定义的load就定义上就Ok了

（2） 在定义loadstep时SPC是约束，LOAD是载荷，注意可能这里弄反了

10创建节点集即节点sets

11*** ERROR # 192 ***

（1）优化设计的topology中优化最小尺寸定义的太小，改大一些可以解决

12 *** ERROR # 842 ***

DTPL or DSIZE card with simultaneous PATRN and MASTER is not supported. violated DTPL or DSIZE id = 2 （1）设计区域不能同时支持模式重复和对称约束
