  We present results for correlators and spectral functions of open charm
mesons using 2+1 flavours of clover fermions on anisotropic lattices. The D
mesons are found to dissociate close to the deconfinement crossover temperature
Tc. Our preliminary results suggest a shift in the thermal D meson mass below
Tc. Mesons containing strange quarks exhibit smaller thermal modifications than
those containing light quarks.
