[Pw_forum] From davcio: error #10

Good evening/morning everybody!

Sorry for being incommunicado for so long (midterm exams -> done!).  So,
I've completed a script to generate all of the files for my ion/metal slab
system, but again I'm running into the davcio error.

Based on Linh's prior suggestions and explanations, I downloaded XCrysDen
and checked out my crystal sizes.  Basically, what I came up with was, given
the original set with the ion at 10.5 angstroms, the cell dimensions 1&3
were 10.5 and 4.89 respectively, that I should lock the celldm(1) in at 10.5
and decrease the celldm(3) as I bring the ion closer to the surface.  So I
measured the ion distance from the top of the cell (in the 10.5 system) and
found it to be approx. 12 angstroms, which I keep constant by decreasing the
celldm(3) by 0.09 for every ion retraction of .5 angstroms.  Thinking I had
solved my issue, I generated all of the input files and submitted them all
for running, and the majority of them promptly crashed (but for some reason
some of the 10-11 ranged systems are still running...).  I'm sure I've
missed something in Linh's initial instructions, so its distinctly possible
that I'm making a stupid error.

I've uploaded a tarball to - - nd.edu/~pholvey/PWSCF.html - - with all of
the input/output files that I've got right now.  If someone could help me
solve this issue, I feel that my calculations are close to being able to run
to completion, and I'd love to figure this out so I can start varying ion
composition.

Thank you so much for all of your help thus far.  This community is awesome!

Many Thanks,
