Hi,
I have prepared input file for strained Graphene Nanoribbon, I am to get it
relaxed. But I receive the following error:
*from davcio : error # 10error while writing to file*
*
*
I am using an orthorombic supercell with periodicity of the ribbon in z
direction. I have tried to make sure the error is not because of
some negligence in setting the output directory. I believe I need to input
celldm() with proper values, being new to QE, i am trying to install
XCrysden as well to figure out that part, but I was wondering if anyone can
suggest the error in the file or possibly suggest the values of celldm that
I should used.
The input file is
&control
calculation = 'relax'
restart_mode = 'from_scratch'
pseudo_dir = '/home/s/schandratre/Espresso/pseudo'
outdir = '/home/s/schandratre/Espresso/strained74'
