[Pw_forum] Error computing Cholesky

[Shruba Gangopadhyay]

Dear Swapnil,
                    Its always better to send the input file here. Because
without your input its very difficult for anybody to understand whats going
wrong. From my experience I can suggest you one thing to check if your
supercell length along anyone of the axis having much high value (like
length of x axis/length along z ~20 or more). I suspect it because you have
a nanoribbon.  In that case you might reduce the ratio and see if you still
getting the error.
                   Cheers
                   Shruba
