[gmx-users] Eror: No parallel Ewald use PME instead!

2014-06-04 Thread Ali Alizadeh
Dear All users, I have encounter this error: - Fatal error: No parallel Ewald. Use PME instead. -- I used 8 cores and gromacs 4.5.5, for doing my calculations. I should use ewald method because my system can not converge using PME it heats up my system. Are there any

Hi, What makes you think the PME algorithm, rather than your choices of settings for it (and twenty other things), is the problem? Mark On Wed, Jun 4, 2014 at 7:57 AM, Ali Alizadeh ali.alizadehmoja...@gmail.com wrote: Dear All users, I have encounter this error: - Fatal

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

Thanks for providing a small fraction of the information for which Justin asked. You stand a much better chance of ever getting an answer from volunteers if you provide more detail than you think could ever be relevant. :-) Mark On Wed, Jun 4, 2014 at 7:39 PM, Ali Alizadeh
