A scalar auxiliary variable unfitted FEM for the surface Cahn-Hilliard equation
Maxim Olshanskii, Yerbol Palzhanov, Annalisa Quaini
The paper studies a scalar auxiliary variable (SAV) method to solve the Cahn-Hilliard equation with degenerate mobility posed on a smooth closed surface Γ. The SAV formulation is c…

Filter stabilization for the mildly compressible Euler equations with application to atmosphere dynamics simulations
Nicola Clinco, Michele Girfoglio, Annalisa Quaini +1
We present a filter stabilization technique for the mildly compressible Euler equations that relies on a linear or nonlinear indicator function to identify the regions of the domai…
