Get data on the pressure on the upper and lower surfaces of a shape

[lehuang696]

I have gotten the pressure around a shape, is there a way to draw and get the pressure data on Visit on the upper and lower surfaces of the shape separately?

Could you elaborate on what you mean? Is pressure a zonal or nodal variable? Are you looking for two different plots, perhaps? Maybe you want to use the clip operator to separate your dataset into upper and lower halves?

Thank you for your reply. I'm sorry I wasn't clear on what I meant, the pressure is zonal variable, the shape is moving in the water, and as you said, I thought I'd get the upper and lower surface pressures of the shape from an existing data.

My best guess is that you'll want to make two plots of the pressure variable, and use the clip operator on each plot to make one of the plots represent upper pressure and the other plot lower pressure. You can do this by unchecking "Apply Operators To All Plots" and then you can apply the clip operator to each plot separately. You'll want to pick a clipping plane that divides the shape neatly into upper and lower sections. You can modify the color maps used for each pressure plot to differentiate them.

Does that all make sense? Is that what you are looking for? Let me know if you have further questions.
