Tecplot9.0画压力系数

Wind

用Tecplot9.0画从Fluent导入的case&data，case是一3D的方柱形建筑物，构成建筑物的封闭面整个为一个区域，我想画每个投影面的压力系数分布。选2D—contour-pressure，通过选取画图的坐标轴选择不同的投影面，但在contour attributes中设置contour plot type为Lines时，发现得到的等压线是两个正对的面迭加在一起的图形，而我想要的只是一个面，请问大虾这怎么解决？是不是只能把建筑物先剖分成不同的投影面？另外我想要无量纲的压力系数，而不是压力值，在Tecplot能象在Fluent中转换吗？

There are options to plot the value by some sample formulaa. such as  p/p0, try it.

3x for ur answering,could u explain it in detail using Chinese?

To modify your data set, follow these steps.
1. From the Data menu, choose Alter.
2. From the Alter menu, choose Specify Equations. The Specify Equations dialog appears as shown in Figure 25-1.
3. Using the Specify Equations dialog, perform the following steps: - Enter the equations. - (Optional) Select the set of zones to alter using the appropriate region of the Specify Equations dialog. The default is to alter all zones. You may skip this step if you want to apply the equation to all zones.
- (Optional) Select the index ranges to alter in the selected zones. You may skip this step if you want to apply the equation to all points of the selected zones.
4. Click Compute to alter the data. This is important. If you do not click Compute, the data values do not change.

关于壁面显示的问题在manual中的那一部分？

选 Field ---> 3D slice-surface detail,在里面进行选择,选择切面的位置,就好了.
可以是IJK方式,也可以是XYZ方式.

好像这样不行，3D slice 只有在将流域内部选取时才可激活；显示的是一个切面，包括流域内部，而不仅是壁面。我试着这样可以实现：2D—contour-cp，style-value blanking填入适当的坐标截断值可以实现控制显示层次。
