We calculate the PCAC mass for (2 + 1) flavor full QCD with Wilson-type quarks. We adopt the Small Flow-time eXpansion (SFtX) method based on the gradient flow which provides us a general way to compute correctly renormalized observables even if the relevant symmetries for the observable are broken explicitly due to the lattice regularization, such as the Poincáre and chiral symmetries. Our calculation is performed on heavy u, d quarks mass (mπ /mρ ≃ 0.63) and approximately physical s quark mass with fine lattice a ≃ 0.07 fm. The results are compared with those computed with the Schrödinger functional method.
