我这个是划分网格后的板,要怎么加垂直于板的载荷? SFA,all,1,PRES,value
自己看看帮助。 直接加垂直压力就行了,选择加在面上就好 找到如下位置:ANSYS HELP->ANSYS ELEMENTS REFERENCE-
>ELEMENT LIBRARY->SHELL63 ELASTIC SHELL。
在INPUT SUMMARY 中,有SURFACE LOADS PRESSURES。
其中,face 1 (I-J-K-L)(bottom,in +Z direction)的意思为:当Load Key=1时,pressure加在由节点IJKL确定的面上,在单元坐标中以+Z方向为正,也可以说垂直指向面IJKL时为正。
至于均布,则将几个值都填成一样的就可以了,或者只填主要参数如VALUE at I。自己多看看帮助文件
