acceleration at high tempreature conditions

Well. Thanks Axel. I don’t know this fix before.
As I tried, when I use this fix, there is an error message,
Creating new pair style: hybrid/long
ERROR: Unknown pair style hybrid/long (…/force.cpp:244)

So I think maybe this fix is not compatible with my kspace setting and I remove my previous setting kspace_style pppm/tip4p 1.0e-5. Then, it shows another error,
ERROR: Pair style requires a KSpace style

This is my pair style setting.
pair_style hybrid lj/cut/tip4p/long 2 1 1 1 0.1546 12.0 10.0 lj/cut 12.0

Again, I think maybe this fix can not run with pair_style hybrid. So I test it in a pure tip4p/2005 water system. My setting is
pair_style lj/cut/tip4p/long 2 1 1 1 0.1546 12.0 10.0
kspace_style pppm/tip4p 1.0e-5

Emmm, another error is like,
Ewald initialization …
ERROR: KSpace style is incompatible with Pair style

When I remove kspace_style pppm/tip4p 1.0e-5, it shows again,
ERROR: Pair style requires a KSpace style

As above, I am really confused of the right use of the command fix tune/kspace. And the manual has no instruction.
Please teach me. Thanks.
