Description
We determine the masses and the pseudo-scalar decay constants of
charmed mesons using non-perturbatively O($a$) improved Wilson quarks.
Our analysis is based on the $N_{\rm f}=2+1$ ensembles using open
boundary conditions, generated within the CLS effort.
The status of results for 2 lattice spacings, $a\approx 0.086$ fm and
$a\approx 0.064$ fm, will be presented. The pion mass is varied from
420 to 220 MeV. This is part of a continuing analysis by the RQCD
and ALPHA Collaborations, aiming at a stable continuum extrapolation
using several lattice spacings. To extrapolate to the physical masses,
we follow both, the $(2m_l+m_s)=\mathrm{const.}$ and
$m_s=\mathrm{const.}$ line.
