Hello Andrew,
See there are the two basic parameters.
DX0:Initial Step Length
DXM: Maximum step length allowed later in the simulation.
But along with them, take care of drms...keep it as low as possible
say 0.00000001.
You sometime may need to use scee, scnb and nsnb. Study them also.
They work when you are considering a big protein and your
electrostatic and non bonded interactions are going very high.
Regards
Ashish
