### Description

Investigation of QCD thermodynamics for $N_f=2+1$ along the lines of constant physics with Möbius domain wall fermions is underway. At our coarsest lattice $N_t=12$, reweighting to overlap fermions is not successful. To use domain wall fermions with the residual mass larger than average physical $ud$ quarks, careful treatments of the residual chiral symmetry breaking are necessary. One of the examples is the chiral condensate where a UV power divergence associated with the residual chiral symmetry breaking emerges with a coefficient not known a priori. In this talk we present first the setup of the computations and then discuss methodologies to overcome potential problems towards the continuum limit in this setup.
