Your mesh size should not exceed ndmx which is probably 3500. I am not sure about the exact number. Check the file radial_grids.f90 in the Module directory for the size of ndmx.<div><br></div><div>Aman<br><br><div class="gmail_quote">

I've been having a first try at using PWscf, after using CASTEP and<br>
various molecular atom-centered codes, and I've managed to perform some<br>
basic calculations with the supplied pseudopotentials. However, when<br>
attempting to perform a test single-point calculation on Pu(OH)_4 with a<br>
plutonium pseudopotential converted over from CASTEP's OTF generator<br>
using the usp2upf tool from the ONETEP site, I get the following error:<br>
<br>
from allocate_radial_grid : error # 1<br>
mesh>ndmx<br>
<br>
Looking at the source suggests that this might be something to do with<br>
some size restriction on the logarithmic radial grids, but I'm really<br>
not sure at all. Switching the plutonium for palladium (for no other<br>
reason than that it seemed like it would fit and was in the PSP library)<br>
produced a working calculation, so it seems like the problem might be<br>
either with the pseudopotential conversion or with some quality of the<br>
pseudopotential being too large/dense/etc for PWscf.<br>
<br>
Does anyone have any suggestions for things I could try, either with<br>
PWscf or to check in the pseudopotential to see what's not working or<br>
make this work?<br>
<br>
(Alternatively/additionally, a source for a good plutonium PBE<br>
pseudopotential that does work would be good too - I've had a try at<br>
both generating my own and using atomic with parameters taken from the<br>
CASTEP OTF one but have had various problems with that.)<br>
<br>
Many thanks,<br>
