Problems running VASP: crashes, internal errors, "wrong" results.

call to ZHEGV failed

#1 Post by opotzel » Sat Jan 30, 2010 1:59 pm

Dear all,
In my calculations I frequently ran into the known "call to ZHEGV failed error". As recomended I commented the line #define USE_ZHEEVX in
davidson.F, subrot.F, and wavpre_noio.F and recompiled
VASP.
This worked fine.
But I wonder what in detail differs from regular calculations.
Because two runs of the same calculation with and without the subroutine differed in energy.
Thanks

I also met this problem. However I do not recompile VASP. I am trying use
IALGO = 48
rather than the default setup for electronic structure SCF processes.
Hope it works well.
