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 $\orderof(a^2)$ scaling for both actions.
