Nacelle Drag Model
Hello, Qblade supporter
This is first time for me to post here.
I am trying to run a simulation inclded nacelle drag model and reading Structual Model Definition in User’s Guide.
However, I could not succeded to operate it and get error message. I made a text file by inserting the code written in User’s Guide and load the file, but it said
“cannot read the file.”
“Structural Model File:
‘Nacelle drag.txt’
could not be interpreted!
Problems:
DISC cannot be smaller than zero or zero!
Please specify blade discretization in the blade data file(s)”
Is there any solutions for that?
Kind Regards
Nanako
Hello Nanako,
if you want to add nacelle drag to a simulation this can only be done as a part of a full structural model definition, see:
https://docs.qblade.org/src/user/turbine/structure.html
It is not possible to only load the nacelle drag definition into the simulation, it needs to be located in the “main” file of the structural model definition.

Hello David,
Thank you for your responcse and suggestion.
I tried to make a load file from the scratch in text but failed to upload, seems to need to be *str file.
Is there any way to mak a str file in QBlade simulation?
Sincerely
Nanako
Hi Nanako,
if you open up any aeroelastic turbine model in QBlade you can export the full model, or only the structural definition, to ASCII text files.
You could use these files as a starting point for a “new” structural model definition if you dont want to start from scratch.
You also find an example for a structural model file in the documentation: https://docs.qblade.org/src/user/turbine/structure.html

Hi, David
I clicked “Turbine Simulation” botton in menu bar and checked “Export Data” then there are some files like below picture.
I exported every file but there are no *str file.
Is there any other ways to extract it?
Sincerely
Nanako
Sorry I didn’t attach any photo, here it is!
Uploaded files:- You need to login to have access to uploads.
Hi Nanako,
if you export the simulation to *.sim files the full turbine definition, of which the structural model is a part, will also be exported.
Aletrnatively you can also only export the turbine definition from the Turbine Design module in QBlade into the *.trb format. In the folder structure that will be created during export you find the structural model files in the /Structure folder.
BR,
David
