Using QEq method for a large system

Hello Everyone,

I want to use QEq method to assign charge for a large system (around 8000 atoms) under Forcite module (Energy Calculation). But the calculation is quite slow, and an error occurs after 10 steps saying the charge group cannot meet the tolerence of 0.1e. Is there any other way to solve this problem?

Thank you.

Best regards,
Anthea
