[Wien] 'SECLR4' - POTRF failed

[Michael Gurnett]

why don't you send the struct file to see if someone can see the problem

Yeah, the user's guide also says this could happen with something wrong
of struct file, I'm still not sure if it is the case though, but
eventually I guess I should go back to basic when something looks very
strange and complicated. Thanks a lot for your advices. I'll try, and
let you know when I solve the problem. 

Sincerely,

Chang-Youn

I'd expect something is wrong in your struct file.

Maybe you have 2 atoms at the same position or 
you entered the lattice parameters in wrong units (Ang vs. bohr) so that
you 
have a very expanded lattice or
one of your RMT values is extremely small (misstyped ?).

Bulk InP supercells with 64 atoms and RKmax=7 should need matrixsizes of
about 5000.

The error comes most likely from approximate linear dependency of the
basis,
but one has to figure out why this happened.
