Doc https://abacus.deepmodeling.com/en/latest/advanced/input_files/input-main.html#relax-nmax says Default: 1 for SCF, 50 for relax and cell-relax calcualtions.
I'm not sure whether it is a doc problem or a bug.
but when running relax without explicitly define relax_nmax in INPUT, the calculation still run with relax_nmax 1 in OUT.xxx/INPUT
byw there is a typo calcualtions
