[CP2K-user] High cutoff for Force Converage

[Hedley Dong]

Hi everyone,
I am test energy and force converage with different cutoff, and the energy 
converged at a reasonable cutoff (~500 Ry). However I found the Force did 
not converge until I increased the cutoff to 800 Ry. I am not sure such a 
high cutoff is reasonable, or can I imporve the force converage with other 
parameters? I upload the input and output, please help!
Thank you!
