Dear gromacs user,
                                Thank you for your previous reply. i am doing  Energy minimization  using Steepest Descent method . When i do that i got the following error

Steepest Descents converged to machine precision in 35 steps,
but did not reach the requested Fmax < 40.
Potential Energy  =                  -nan
Maximum force     =  2.23324790984423e+09 on atom 9566
Norm of force     =                  -nan

How to rectify the above error?
With Regards 

S.Vidhya sankar
