I will focus here on using the GPAW to do very basic calculations on the desktop. I will show you how to setup GPAW on your computer, create a new structure (we will focus on small molecules here), setup a calculation, perform the calculation and analyze the results.
If you have Python installed, type this in your command line: pip3 install gpaw
This will install GPAW on your computer. So easy! If you don't have python installed, or if you are having any difficulties, let's discuss during the tutorial.
