“High Order Compact Mimetic Methods and Discrete Energy Decay in 2D Wave Motion”
—————————————————————————————————————————————————

Mimetic differences operators, Div, Grad and Curl, have been constructed to provide a high order of accuracy in numerical schemes that mimic the
properties of their corresponding continuum operators; hence they would be faithful to the physics. However, this faithfulness of the discrete
basic operators might not be sufficient if the numerical difference scheme introduces some numerical energy increase, which obviously result
in a potentially unstable performance. We present a high order compact mimetic scheme for 2D wave motions and show that the energy of the
system is also conserve in the discrete sense.
