ansys 布尔减操作
1）通过定义原点、板宽和板高定义矩形,其操作如下：
GUI：PreProcessor > Modeling > Create > Areas > Rectangle > By 2 Corners 弹出Rectangle by 2 corners对话框,填入相应数值
2）生成圆面
首先在矩形面上生成圆,然后挖去生成圆孔.生成圆面得操作如下：
GUI：PreProcessor > Modeling > Create > Areas > Circle > Solid Circle
弹出 Solid Circular Area对话框 输入圆面几何参数
3）生成圆孔GUI：Processor > Modeling > Operate > Booleans > Subtract > Areas
先选择矩形面为Base Area,单击OK按钮,然后选择圆,单击OK按钮.布尔操作结束
在用进行操作时,选择矩形面为Base Area,单击OK按钮,然后选择圆,没有出现另一个ok按钮,回车出现
Warning：Some of the requested areas to be operated on were included in the selected set to be subtracted.These areas have been removed from the area to be subtracted list.
请问是怎么回事啊,
