I am new to md and gromacs. According to the manual and some the
tutorial, one can set either temp coupling or pressure coupling or both
at the same time. Does the temp coupling alone mean to use NVT ensemble
and pressure alone NPT ensemble? What is it when use both coupling?
If I turned off pressure coupling in my md but temp coupling on, I got
about average pressure of -1000 bar. What does that mean? Is the density
of my system too high? If it is, how should I change it?
Thanks for any input.
