对桩顶施加一冲击荷载,命令流如下.总是出现一些问题,高手帮我看下吧


/FILNAME,PILING,0
!指定工作名称
/TITLE,ANALYSIS OF PILING
!指定图形显示标题

/PREP7
ET,1,SOLID164
MP,DENS,1,2500
MP,EX,1,2.7E10
MP,NUXY,1,0.2
BLOCK,,0.25,,0.25,,20
!桩体几何建模
VATT,1,,1,0
!指定划分单元的属性
ESIZE,0.05
VMESH,ALL
/VIEW,1,1,1,1
/REP

NSEL,S,LOC,-0.01,0.01
!选择桩底面的所有节点
D,ALL,,,,,,ALL,,
!约束桩底面的所有节点
ALLSEL,ALL
*DIM,TIME,ARRAY,5,1,1,
! 定义时间数组
TIME(2,1,1)=0.00125
TIME(3,1,1)=0.0025
TIME(4,1,1)=0.00375
TIME(5,1,1)=0.005

!定义冲击荷载数组或曲线
*DIM,FORCE,ARRAY,5,1,1,
!定义荷载数组
FORCE(2,1,1)=25000
FORCE(3,1,1)=50000
FORCE(4,1,1)=25000
FORCE(5,1,1)=0

NSEL,S,LOC,Z,19.99,20.01
!选择桩顶面的所有节点
ESLN,S
!选择桩顶面的所有单元
CM,LOAD,ELEM,
!形成桩顶单元组元LOAD

!通过数组形式向桩顶面施加冲击压力脉冲荷载
EDLOAD,ADD,PRES,0,LOAD,TIME,FORCE,0,

ALLSEL,ALL
FINI

/SOLU
TIME,0.015
EDRST,100
EDHTIME,100
EDOPT,ADD,blank,BOTH
SOLVE
FINI


错误文件里有这样的提示
*** WARNING ***
CP =
4.266
TIME= 19:45:19

The labels AX, AY, AZ, VX, VY,VZ are not allowed in the D command for


Explicit Dynamics Applications.
Some of these constraints were


specified but will not be used in the solution.
Try using the EDLOAD


command instead.

这个例子是在ansys/ansys ls-dyna环境下进行的

starbo

D,ALL,,,,,,ALL,,
这个命令有错误
改为D,all,all,0试试
