Combining Time and Mimetic Spatial Discretizations Steinberg, Stanly
Description
The problem is to combine explicit time and mimetic spatial discretizations for wave equations so that the energy is conserved. It is easy to see that intuitive discretizations of the energy are not conserved. However it is possible to find conserved quantities that depend on the time step that are conserved and converge quadratically in the time step to the classical energy.
