Dear all,
When optimise the nonbonded interactions, some of them don't converge, like 
shown in the picture. The system is a bulk system and has no crystal.
I have tried several solutions:
1. change the scale factor (1.0, 0.7, 0.5);
2. change the initial guess by using high temperature (default 458 K, high 
T=600 K) in the setting.xml (nonbonded.xml as attached);
3. the order of optimisation.
All of them have the same results.
How can I solve this problem?
Best regards,
Zidan
