[gmx-users] potential energy =nan

[Sheyore Omovie]

I am doing an Energy Minimisation run for two polypeptides in a box. I get 
the range checking error, variable ci= .... and the simulation crashes. 
After changing ns_type to simple, the simulation is running, but very slowly 
and the first few steps return Epot=nan.
What could I have done wrong?
