Popis:	39th International Symposium on Lattice Field Theory, Lattice 2022, Bonn, Germany, 8 Aug 2022 - 13 Aug 2022; Proceedings of Science / International School for Advanced Studies (LATTICE2022), 408 (2023). doi:10.22323/1.430.0408 We present two calculations of heavy quark physics, with respectively non-perturbatively improved Wilson and twisted mass Wilson fermions, both on $N_{\mathrm{f}}=2+1$ CLS configurations with open boundary conditions. We evaluate those discretisations through a Ward identity on the three-point functions. We also check the universality of our continuum results. All our results are compatible with an $O(a^2)$ scaling for both actions. Published by SISSA, Trieste
