Dear all,

Hope you have a good day.

Recently, I received a query about warning message after running the Forcite job.

It says:

Warning. The PPPM method has been chosen for the electrostatic terms.

The current implementation assumes that all interactions are of the form F(1/Rij), but the forcefield contains other terms.

They will all be treated as F(1/Rij).

He used Dreiding FF in order to figure out the Hydrogen bonding force, and the charge was calculated through DMol3(Use current).

The Electrostatic summation scheme was PPPM for using the GPU.

Is the error message means a critical error for the calculation?

If so, how could it be corrected?

Thank you.

Best regards,

Rakhoon Choi
