Dear all,

I am trying to run an AIMD run with a poly-oxo anion and water in CP2K, and I get a "CPASSERT failed motion/thermostat/thermostat_utils.F:1846" error immediately after the first SCF cycle. Any suggestions on how to fix this would be highly appreciated. 

Note: I was able to run the a slightly different system (same atoms, but a different connectivity in the poly-oxo anion) successfully before.

Thanks,
Hemanth

Hi

most likely --- your thermostat region definitions is no longer aligned with your molecule definitions.

regards
