我模拟的是一个板，四边固支，采用shell 163命令如下
LSEL,S,LOC,X,0.05
LSEL,A,LOC,X,-0.05
LSEL,A,LOC,Z,0.04
LSEL,A,LOC,Z,-0.04
DL,ALL, ,ALL,
我模拟的时候总是出现下面的提示，怎么避免
Although VX,VY,VZ and AX,AY,AZ may appear as DOF's they are not
actually physical DOF's. However, these quantities are computed as
DOF solutions and stored for post-processing.
是不是采用的命令有误？
