suavecode / tutorials Goto Github PK

Hi all,
First, thank you for this powerful tool and the tutorials.

I am trying to lauch the BWB_CFD tutorial and SUAVE returns an error (installed : VSP 3.11.0).
I am under the impression that in get_vsp_areas (Input_Output/OpenVSP/get_vsp_areas.py) the reading of the file Unnamed_CompGeom.csv crashes. The file format may have changed. Here is the contents of the file :

Name, Theo_Area, Wet_Area, Theo_Vol, Wet_Vol
main_wing0,3124.876446,3124.876446,3801.754585,3801.754585
Totals,3124.876446,3124.876446,3801.754585,3801.754585

Tag_Name, Tag_Theo_Area, Tag_Wet_Area
main_wing0,1562.438223,1562.438223
main_wing1,1562.438223,1562.438223

The subsurfs calculations added (I don't know how to disable this calculation from the python code)

I changed the reading of the file (stop when only one element in split string = '\n') : I supposed that the area is one calculated in the first section and not subsurfs.

With this modification, the result I obtained :

Can you confirm the provided data with the new OpenVSP application ?

aerodynamics.settings.discretize_control_surfaces = True

The BWB has not yet been updated to include a tip segment.

This was initially in the main repository.

When I tried running the example code, I received this error message:

Importing "Mission_Plots" module in tut_mission_B737.py should be found nested under Plots.Performance.Mission_Plots line 31

from SUAVE.Plots.Performance.Mission_Plots import *

instead of

from SUAVE.Plots.Mission_Plots import *

I downloaded and installed SUAVE follow the Developer instructions at https://suave.stanford.edu/download/standard_install.html and downloaded the tutorial
from Github at https://github.com/suavecode/SUAVE. and the SUAVE tutorials from https://github.com/suavecode/Tutorials. When I run either the tut_mission_B737.py or tut_solar_uav.py tutorial examples using Anaconda Spyder from the tutoral folder, I get The following Error:

During handling of the above exception, another exception occurred:

AttributeError: 'Config' object has no attribute 'propulsors'

The tut_mission_B737.py code seems to setup a turbofan at line 402, but I can find nowhere in the example or in the SUAVE base code where this is assigned to 'propulsors.

I am a relatively new python user, but the SUAVE egg seems to be properly loaded in to my E:\Users\Bob\anaconda3\Lib\site-packages folder SUAVE-2.4.0-py3.8.egg.

Some graphs generated from the example code have unclear labels, see the attached image for an example

I don't know if I am not doing the right thing or what kind of problem, please help me.
thanks~！

I've noticed several small mistakes in the code for the solar UAV optimization tutorial:

Optimize.py, line 53: I guess wing_area should be Units.meter**2 and not Units.meter, right? (just like for the regional jet optimization tutorial)

Procedure.py, line 69: Change the dynamic pressure based on the, add a factor of safety Not quite sure what word is missing there.

If I find more I'll add them here.
