采用如下命令流定义随时间变化的正弦位移载荷，会产生如下错误代码很是费解啊，求高手解答: *** ERROR *** CP = 158.828 TIME= 23:24:33 Present time -4.999999923E-05 is less than or equal to the previous time 0 in a transient analysis. *** ERROR *** CP = 159.156 TIME= 23:24:47 The step data was checked and there were errors found. Please check output or errors file ( D:\ANSYS anli\default.err ) for messages. *** WARNING *** CP = 160.484 TIME= 23:24:49 Input time should be greater than zero. *** ERROR *** CP = 161.969 TIME= 23:24:51 Present time -8.660253949E-05 is less than or equal to the previous time 0 in a transient analysis. /COM,ANSYS RELEASE Release 17.0 BUILD 17.0 UP20151214 23:29:49 命令流如下: !***************表数组赋值*********************** *DIM,LOAD,TABLE,7,1,1,Time,dispaacement, dt=1/60 PI=3.1415926 LOAD(0,0,0)=1 *DO,I,1,7,1 LOAD(I,0,1)=(I-1)*dt *ENDDO *DO,I,1,7,1 LOAD(I,1,1)=-0.0001*SIN(10*PI*(I-1)*dt) *ENDDO !***************表数组调用*********************** dt=1/60 *Do,i,1,6 tz=LOAD(I*dt,0,1) lz=LOAD(I*dt,1,1) VSEL,S,,,6 NSLV,S,1 D,ALL,,lz,,,,UX,UY,,,, time,tz ALLSEL solve *enddo |
