How to update blade structure data table?
Hi,
I’m new to QBlade, If anyone could help on how to update blade structure data table when a blade structure design changed?
How could I generate a “Blade xxxx.str” data file accordingly?
Thank you.
Hi,
to generate the data that i required for the cross sectional data table in QBlade you have a few options:
1. Use QFEM to generate simple blade designs, based on isotropic material data.
2. Use analytical functions for simple shaped to generate cross sectional data
3. Use a specialized software tool, such as BECAS, VABS or similar.
BR,

Thanks David, I have an open-sourced blade model made by NuMAD, if I can get a corresponding blade cross sectional data table by Ansys?

Hi,
I cannot comment on how to extract the required cross-sectional properties from general purpose FEA tools, but it should be possible.
The required cross-sectional properties for the blade beams, depending on the type of beam, are found in the documentation:
https://docs.qblade.org/src/user/turbine/structure.html#structural-definition-of-bodies
Other aero-elastic wind turbine simulation codes, such as OpenFAST, HAWC2 or Bladed, require similar cross sectional properties, so there should be some literature available on this topic.

David

Thank you for your patient guidance, David. Let me have a try on this and come back to you later.
