加载位移约束的时候出现的奇怪的问题
在给四个node加载位移约束的时候，我是GUI操作的，按住了ctr键，选了除y方向旋转自由度以外的所有自由度。但是选完确定时系统弹出的提示是：A duplicate dof label(velz) was found on the D command.不知道这是什么原因？请高人指点一下，谢谢！ ctrl key in ansys is used to rotate the model, not to do a multi-select as in autocad.as far so the warning message, you can totally figure it out by yourself when you know the syntax of D command. look it up in ansys online help.
