CCBlade unit test fails #1

Closed matsupe closed 9 years ago

matsupe commented 9 years ago

The installation of CCBlade is difficult.

Could you please provide more details about the Python software you used on your system?

I installed:

MinGW gfortran Fortran compiler, Python 2.7, NumPy, SciPy, and zope.interface (last 3 for Python 2.7) on my Windows PC.

The installation was successful but I get the following error when I run the unit test "python test/test_ccblade.py" :

Matias@MATIAS-PC C:\CCBlade $ python test\test_ccblade.py

This is not an installation failure, but a testing one. I am seeing the same issue. Something must have changed in one of the recent commits. Give me a few days to look into this.

I've now fixed this issue. Thanks for pointing it out. Please update (and update airfoilprep)
