Yes, the simulation goes well when a ligand is close to the heme.
But when the protein has no ligand, the free water is easy to collapse 
nearby the heme.
I found the parameters(different to zero) for Fe2+ in OPLS force field. 
Might I use the parameters for the Fe since I modified the charge from +2 
to +1.
