Dear GROMACS Users: As I mentioned, I got the following log file when I used the "mdrun" command. I installed GROMACS on my virtual machine. Is there any solution to this problem?
Thanks! Andy ++++ PLEASE READ AND CITE THE FOLLOWING REFERENCE ++++ H. J. C. Berendsen, D. van der Spoel and R. van Drunen GROMACS: A message-passing parallel molecular dynamics implementation Comp.
