Hello, NAMD:

I am still stucked by the velocity errors. With the suggestions from
others, I have modified the '.conf' file: delete the
'cellBasisVectors', padding my OME grid sizes a bit more; choose
'useflexsibleCell no'. All these efforts allow the simulation to a bit
longer, but still stopped premature:

I have included my .conf file as an attachment. Thanks for advice.
