Good evening/morning everybody!<br><br>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.<br>
<br>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.<br>
<br>I've uploaded a tarball to - - <a href="http://nd.edu/~pholvey/PWSCF.html">nd.edu/~pholvey/PWSCF.html</a> - - 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.<br>
<br>Thank you so much for all of your help thus far. This community is awesome!<br><br>Many Thanks,<br><br>Patrick<br>University of Notre Dame<br><br><div class="gmail_quote">On Sat, Feb 20, 2010 at 9:02 AM, Ngoc Linh Nguyen <span dir="ltr"><<a href="mailto:nnlinh@sissa.it">nnlinh@sissa.it</a>></span> wrote:<br>

</div>I suppose that you have been not familiar with Xcrysen package :D.<br>
<br>
Firstly, you should find the lattice constants of the given slab, then<br>
calculate the positions of atoms belong to these parameters.<br>
By assuming that the values of the positions of atoms are right and<br>
present in your input file, I visualize the input file by Xcrysden<br>
package .<br>
- Then, we displayed the Crystal cells (Display -> Crystal Cells).<br>
Here, you can be seen that, with the celldm(1)=30, the atoms are located<br>
just at the conner of hole supercell.<br>
- You duplicate the supercell be long to Ox or Oy (Modify -> Number<br>
of unit drawn), you can see that your slab is not continuous belong to<br>
Ox and Oy axis because the supercell sides are to lager. Thus, I should<br>
decrease celldm(1) to keep continuousness of the slab. Of couse, my<br>
values maybe not precise completely, so you should recalculate so that<br>
the atom positions agree with periodicity.<br>
Moreover, you should also recalculate the Celldm(3) value associate with<br>
the new Celldm(1) one. (I suppose you've known how to get a suitable of<br>
Celldm(3))<br>
<div class="im">> and why they worked while the prior ones did not.<br>
</div>You can see that when Celldm(1) is too large and a wrong value, the G<br>
cutoff , FFT grid values are very larger, and an insufficient virtual<br>
memory could be happened.<br>
<div class="im">> Further, I'm going to be moving the ion closer to the surface in<br>
> future calculations. Will I have to recalculate those numbers or am I<br>

</div>The Celldm(1) value should be fixed, because it does not relate to ion<br>
moving, but Celldm(3) maybe changed if you move too far from surface<br>
with respect to the Oz side of supercell.<br>
<br>
Linh<br>
<div class="im">> Many thanks,<br>
