Dear all,

I am trying to run a simulation of the interaction between two HEME in water. I have done it without problem, but when I use the calculated charge of HEME atoms from ab initio calculation I have problem.

The enery minimaization was run without problem with the results:

Steepest Descents converged to Fmax < 2000 in 84 steps
Potential Energy  = -1.5738966e+05
Maximum force     =  1.8819653e+03 on atom 77
Norm of force     =  9.0745400e+03

When I try to run position restraint dynamic the process end with error as follow:


check your energy components. are the bonds and angles low enough (this is in the minimization). How do the values differ in the dynamics?
