Dear all,

I have just started using Quantum ESPRESSO as my main research involves molecular dynamics simulations. I am working on relaxing a system consisting of a polymer and CO2. I would like to determine if any hydrogen bonds are formed between them. I was wondering if my input file is correct for this calculation. Below is my input:

&control
    calculation='relax',
    restart_mode='from_scratch',
    prefix='PPN-CO2',
    pseudo_dir = ''
    outdir=''
  tprnfor = .true.
/
 &system
    ibrav=  1,
  celled(1) = 120.0,
  nat = 99,
    ntyp = 4,
    ecutwfc =50, ecutrho =500,
    vdw_corr = grimme-d3,
 /
 &electrons
    conv_thr = 1.0d-8
 /
 &ions
 /
