[Pw_forum] Regarding reliability of GGA+SOC result

[paresh rout]

Dear all,
I have a query regarding reliability of GGA+SOC result when one restart the
calculation from the LDA+SOC potential. I use *pbe fully relativistic*
pseudopotential for my calculations. But the SCF did not converge with
PBE+SOC . Hence I choose input_dft="LDA" and did the calculation which
leads to a fine convergence. Then, I restart my calculation (from lda+soc
generated potential) again switching back to PBE through input_dft="PBE"
 and the scf finally converged with GGA+SOC . But I do not understand how
much I can rely on this result. Any help would be highly appreciated .
