Hello QE users! I have been testing the convergence of energy in a Cu2O slab, I ran a lot of calculations with differents parameter, but, when I am doing the ecutwfc test, from 15 Ry to 200 Ry, i have a problem/error when the ecutwfc is 65 or 70. All others do not have any problem. The error is:
Estimated max dynamical RAM per process > 295.16MB Estimated total allocated dynamical RAM > 1180.62MB %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Error in routine ggen 1 (299008): too many g-vectors %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% stopping ... I do not know why it is the error, neither how can i fix it, i read the forum, but always the answers are like as: " verify that you haven't given in input weird parameters (cutoff, fft dimensions) for the G-vector grid, or very strange cells". In my case, the input file and the geometry is the same for all calculations, i only change the value of ecutwfc. The calculations does not have any problem when ecutwfc is 60 or 75 Ry... I do not know what to do for fix it... Any suggestions? Regards
