1,照着一本输学习ANSYS,在输入地震波时提供了如下命令流:nt=150*dim,time,,nt*dim,ac_x,,nt*dim,ac_y,,nt*dim,ac_z,,nt*vread,time,time,txt,,ijk,nt(f6.2)*vread,ac_x,ac_x,txt(f6.2)*vread,ac_y,ac_y,txt(f6.2)*vread,ac_z,ac_z,txt
nt=150
*dim,time,,nt
*dim,ac_x,,nt
*dim,ac_y,,nt
*dim,ac_z,,nt
*vread,time,time,txt,,ijk,nt
(f6.2)
*vread,ac_x,ac_x,txt
(f6.2)
*vread,ac_y,ac_y,txt
(f6.2)
*vread,ac_z,ac_z,txt
(f6.2)
我已经按书上指示将三向地震荷载的时间点和荷载数值写入时间文件 time.txt和荷载文件ac_x.txt,ac_y.txt,ac_z.txt中且放入工作目录中,可是运行命令流时出现如下错误:
In the graphical user interface the VREAD command can only be executed from an external file such as
/INPUT or *USE. the command is ignored.
(F6.2) is not a recognized SOLUTTON command,abbreviation or macro. thisc ommand is ignored.
请问这是什么意思?哪里出了错误?尤其(F6.2)是什么意思?
2,在GUI操作时
在执行Utility>parameters>arrar parameter>read from file 弹出对话框后有一项enter format surrounded by ( ) 该输入什么?
3,一般输入地震波时应该怎么操作?
一个人学习真苦闷,没有人可以讨论,希望大家可以帮我,万分感谢!!
