I am getting this error: Step 0: The total potential energy is 2.34679e+14, which is extremely high. The LJ and electrostatic contributions to the energy are 2.34679e+14 and -315983, respectively. A very high potential energy can be caused by overlapping interactions in bonded interactions or very large coordinate values. Usually, this is caused by a badly or non-equilibrated initial configuration, incorrect interactions, or parameters in the topology. I changed the .mdp files but still could not resolve the error. I have attached the complex.gro file please review it.
