Hey, guys, I am trying to write some Python Code to plot Cp with Tecplot output data. Right now, I am able to get right plot in Python. In the next step, I am trying to output the x,y/z,and Cp information into Excel and plot the airfoil shape and Cp. However, I find that I have no idea how to put those information in the right sequence and get a proper plot.

I'm not sure I can help you with getting the data in the proper form for Excel, but pulling the data out of Tecplot using PyTecplot is pretty easy.
Here's some example PyTecplot code, that pulls the x,y,z,Cp values out of one of the example datasets. Code:
import tecplot as tp tp.new_layout() dataset = tp.data.load_tecplot(r"C:\Program Files\Tecplot\Tecplot 360 EX Beta\examples\OneraM6wing\OneraM6_SU2_RANS.plt") xvals = dataset.zone('WingSurface').values('x').as_numpy_array() yvals = dataset.zone('WingSurface').values('y').as_numpy_array() zvals = dataset.zone('WingSurface').values('z').as_numpy_array() cp_vals = dataset.zone('WingSurface').values('Pressure_Coefficient').as_numpy_array() Scott |
