[gmx-users] output of 'mdrun' with conjugate gradient

[Karina Mai]

Dear gmx-users,

I am searching for hints to understand the gromacs output
of a conjugate gradient 'mdrun':

Step and time 0.00000 are occuring twice, each of them showing different
energy values, why ? 
What is algorithmically behind it ? How can two different calculations
get
the same time and step number 0 ?

Thanks for helping,
-K
