Bonds rotated >90 degrees warnings/1-4 interactions/WMCNBS ending in segfault.

Haven't had a chance to reproduce as I don't take periodic backups on this machine
EDIT: ok, I could do that if I undeleted relevant queue entry (too lazy to do that just yet)

Log excerpt follows (full log available upon request).

Code: Select all

[05:06:50] Completed 175000 out of 250000 steps  (70%)
[05:14:42] Completed 177500 out of 250000 steps  (71%)
[05:22:34] Completed 180000 out of 250000 steps  (72%)
[05:30:27] Completed 182500 out of 250000 steps  (73%)

Step 27432900, time 54865.8 (ps)  LINCS WARNING
relative constraint deviation after LINCS:
rms 0.360012, max 18.521997 (between atoms 7103 and 7104)
bonds that rotated more than 90 degrees:
 atom 1 atom 2  angle  previous, current, constraint length
   7100   7102   90.0    0.1090   1.9903      0.1090
Warning: 1-4 interaction between 7102 and 7104 at distance 3.926 which is larger than the 1-4 table size 2.200 nm
These are ignored for the rest of the simulation
This usually means your system is exploding,
if not, you should increase table-extension in your mdp file
or with user tables increase the table size

This usually means your system is exploding
That was the huge explosion I heard coming from so far away ? :lol:
