Aims: We aim to explore the influence of thermal conduction on the attenuation of the fundamental standing slow magnetoacoustic mode in a two-dimensional (2D) potential arcade that is embedded in a gravitationally stratified solar corona. Methods: We numerically solve the time-dependent magnetohydrodynamic equations to find the spatial and temporal signatures of the mode. Results: We find that this mode is strongly attenuated on a time-scale of about 6 waveperiods. Conclusions: The effect of non-ideal plasma such as thermal conduction is to enhance the attenuation of slow standing waves. The numerical results are similar to previous observational data and theoretical findings for the one-dimensional plasma.
