用过这个/config,nres,20000 命令怎么没用呢？

snowhill

超过1000步就算不了了，使用时有什么要求么？

snowhill

第一次
solve
之前使用就ok了

ambotao

我是这样用的
fini
/clear
/prep7
... ...
allsel,all
/rep
fini

/CONFIG,NRES,20000    ! 实际我用了3000步
/soul
antype,trans
... ...
lssolve,1,3000
save
fini
这样写有问题么？
的确用在了第一次solve之前，可是也不能生效，怎么回事？
经高人指点，改为如下就可以了：
fini
/clear
/CONFIG,NRES,20000    ! 实际我用了3000步
/prep7
... ...
allsel,all
/rep
fini

/soul
antype,trans
... ...
lssolve,1,3000
save
fini
另外，可以参考help中vme6例题

wxpand2004

其实我想问一下/config,nres,10000
这个命令是什么作用？
我第一次遇到，但是help里面没找到！
还请指点！

看样子是改变ansys内部默认的最大载荷步数

xiaoling0913

是设定计算过程中写入结果的次数，一般用在瞬态分析里面，程序默认的是1000次，如果分的时间部超过一千次，就得自己设置一下写出的最大次数了，要不然程序会计算过程中会报错。

一定要在刚打开ansys时马上输入/config,nres 才管用，千万不要读入任何模型

同意楼上的，在中间输入这个命令是无效的

帮助文件：
/CONFIG
/CONFIG, Lab, VALUE
Assigns values to ANSYS configuration parameters.
Lab
Configuration parameter to be changed:
  
NRES
 — 
VALUE is maximum number of results sets (substeps) allowed on the result file. Defaults to 1000. For MFX analyses, defaults to 5000. Minimum is 10.
NORSTGM
 — 
Option to write or not write geometry data to the results file. VALUE is either 0 (write geometry data) or 1 (do not write geometry data). Useful when complex analyses will create abnormally large files. Default is 0.
NBUF
 — 
VALUE is the number of buffers (1 to 32) per file in the solver. Defaults to 4.
LOCFL
 — 
File open and close actions. For VALUE use: 0 for global (default); 1 for local. Applicable to File.EROT, File.ESAV, and File.EMAT. Typically used for large problems where locally closed files may be deleted earlier in the run with the /FDELE command.
SZBIO
 — 
VALUE is the record size (1024 to 4194304) of binary files (in integer words). Defaults to 16384 (system dependent).
ORDER
 — 
Automatic reordering scheme. For VALUE use: 0 for WSORT,ALL; 1 for WAVES; 2 for both WSORT,ALL and WAVES (default).
FSPLIT
 — 
Defines split points for binary files. VALUE is the file split point in megawords and defaults to the maximum file size for the system.
MXND
 — 
Maximum number of nodes. If not specified, defaults to 100 at first encounter. Dynamically expanded by doubling, even at first encounter, when maximum is exceeded.
MXEL
 — 
Maximum number of elements. Default and expansion as for MXND.
MXKP
 — 
Maximum number of keypoints. Default and expansion as for MXND.
MXLS
 — 
Maximum number of lines. Default and expansion as for MXND.
MXAR
 — 
Maximum number of areas. Default and expansion as for MXND.
MXVL
 — 
Maximum number of volumes. Default and expansion as for MXND.
MXRL
 — 
Maximum number of sets of real constants (element attributes). Default and expansion as for MXND.
MXCP
 — 
Maximum number of sets of coupled degrees of freedom. Default and expansion as for MXND.
MXCE
 — 
Maximum number of constraint equations. Default and expansion as for MXND.
NOELDB
 — 
Option to write or not write results into the database after a solution. When VALUE = 0 (default), write results into the database. When VALUE = 1, do not write results into the database.
DYNA_DBL
 — 
Option to invoke the double precision version of the explicit dynamics solver LS-DYNA. When VALUE = 0 (default), the single precision version is used. When VALUE = 1, the double precision version is used.
STAT
 — 
Displays current values set by the /CONFIG command.
VALUE
Value (an integer number) assigned to the configuration parameter.
