Variational Multiscale Modeling with Discontinuous Subscales: Analysis and Application to Scalar Transport
Christopher Coley, John A. Evans
We examine a variational multiscale method in which the unresolved fine-scales are approximated element-wise using a discontinuous Galerkin method. We establish stability and conve…
