Hi Yingchun,
I don’t think decrease the EPS_DEFAULT value would significantly help to 
solve the explosion problem. Normally, a CUTOFF of 1200 is definitely too 
large for a system that only have CHO elements. As I posed above 600Ry 
seemed was a not bad choice, right. But it didn’t work. I would try a 
calculation with EPS_DEFAULT of 1.0e-14 a few days later. I don’t have time 
and resources right now. And I will pose results to let you know.
