I did as it was said on the website, that is I started with a bigger cell and also added the cell_factor=5 in my input file. It ran for some time but crashed and gave me the following error:

task #         1
     from ggen : error #     74728
     too many g-vectors

Best,

Dear all QE users and developers,

I want to do a "vc-relax" calculation, however I get the following error:

task #         0
     from scale_h : error #         1
     Not enough space allocated for radial FFT: try restarting with a larger cell_factor.
