Dear Mark,

Thank you for your reply.

When you do not change any parameters except one thing in mdp file(PME to

ewald as the paper said that)and then your system converges, for me it
means the problem is related to

choosing the right method for  calculation of the electrostatic
potential energy. What's your point on it?

What makes you think the PME algorithm, rather than your choices of
settings for it (and twenty other things), is the problem?
