Answer 1

sect,2,shell,, 指的是定义编号2号壳体单元
secdata,0.015,1,0,3 指的是命令:SECDATA, Sec_IDn,XLOC,YLOC,ZLOC
其中Sec_IDn---已经定义的梁截面识别号，用于端点1(I)和2(J)截面ID。XLOC,YLOC,ZLOC---整体坐标系中Sec_IDn的位置坐标。
secoffset,MID 指的是 SECOFFSET, Location,OFFSET
Location---偏移也有4个选择位置，分别为:TOP:壳节点偏移到顶面。MID:壳节点偏移到中面。BOT:壳节点偏移到底面。USER:用户定义，偏移梁由OFFSET指定。
OFFSET---仅当Location=USER时，相对于中面的偏移距离。
seccontrol,0,0,0,0,1,1,1指的是SECCONTROL命令控制横截面剪切刚度(缺省值)。
