Energy Cutoff Convergence - init. calc. relax Murnaghan fit / BCC
================ 

In this directory we perform a standard total energy convergence study of the plane wave cutoff energy. 

1. Take a look at all the input files for QE, `pw.Fe-BCC-LDA.scf.in.temp`. 
   Are there required inputs missing? Why? Look in the `run-convergence-loop.sh` script. 
   What is it doing? What functional, and k-grid are being used? 
   Look for key input flags described in the QE manual.

2. Start the calculation with `sbatch run-convergence-loop.sh`.

3. After the run finishes check the ENERGY.out file and look at the 
   data given shown, how did we get it? 

4. Leave this folder and continue to the next.
