BWB.py tutorial

[Zhussip Zhursimbay]

Hello

I am a new user of SUAVE and want to run BWB.py file. I already installed suave 2.5.2 and Openvsp 3.6.1 via Python and now starting running code in spyder. However, I had a following error: 

runfile('C:/Users/ASUS/.spyder-py3/temp.py', wdir='C:/Users/ASUS/.spyder-py3')

Could you please help me ASAP?

Hi,

It looks like it's not finding the file. Make sure it's local to the directory you're running from, i.e. move the file or your scripts.
