Hi Wien2k users,

My calculation was crashed when I was  calculating the water absorption problem on the TiO2 surface. It is the  10th version of Wien2k. I ran the code in parallel mode via command  line.  Then I got the report said lapw2 crashed with Fermi5 error.

 I have checked these files:

 The case.dayfile:
 lapw2Q -p   (15:00:25) running LAPW2 in parallel mode
 **  LAPW2 crashed!
 0.346u 0.150s 0:00.48 102.0%    0+0k 0+0io 0pf+0w
 error: command   /opt/Virgin_10.1/lapw2Qpara lapw2Q.def   failed

>   stop error
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
the lapw2.error:

Error in LAPW2
 'RTBIS' - Root must be bracketed for bisection.
**  testerror: Error in Parallel LAPW2

 I could not solve this problem by myself. Does anyone know what happened?
 
 thanks,
 Andy
