CCBlade running test #10

Closed Jjzm99 closed 5 years ago

Jjzm99 commented 5 years ago

Hello I was trying to install ccblade using the comand python setup.py install, and after the installation was completed I started the test with the comand python test/test_ccblade.py but an error appear Import Error: DLL load failed: It couldnt to find the esoecified module

If you ccould help me with this, I ll apreciated so much Im trying to use this program for a research . Thanks for your time

I'll need more information to help you resolve this. Please provide the full error message and any other information about your setup and how you installed CCBlade.

It's failing to load _bem which is the compiled fortran blade element momentum solver. The problem is almost definitely your fortran compiler. Make sure you have MinGW installed and properly configured as discussed here https://nwtc.nrel.gov/WISDEM and https://nwtc.nrel.gov/system/files/Windows%20OpenMDAO%20Install%20Tips_04062015.pdf

If you're still running into problems after fixing your compiler, please share the full output from reinstalling CCBlade using python setup.py install --force

A fortran compiler was not found, so either A) its not installed, B) its not on your windows Path, or C) you did not configure python to use MinGW. Also you're not installing in an active Openmdao environment. Please follow the Wisdem installation instructions very closely as missing any step could cause the installation to fail.

Jjzm99 commented 5 years ago

Yeah thanks it works, the tests But I have a question:

How can I create data files for diferent airfoils or where can I find the data set with more airfoils ?

evan-gaertner commented 5 years ago

That's outside the scope of WISDEM and CCBlade. However, NREL has a large database of airfoil data and a commonly used tool for generating airfoil polars is XFoil. https://wind.nrel.gov/airfoils/AirfoilData.html https://web.mit.edu/drela/Public/web/xfoil/ There are also airfoil files for different wind turbine blade designs in the r-test repo of OpenFAST https://github.com/OpenFAST/r-test/tree/master/glue-codes/fast
