WVAdaptiveDamping

Adaptive small-scale damping

---

Declaration

WVAdaptiveDamping < WVForcing

Overview

This damping operator is a linear closure designed not to mix geostrophic and wavemodes. This requires setting the diffusivity equal to the viscosity. It also uses the spectral vanishing viscosity filter to prevent any damping below a particular wavenumber.
