Hybrid high-order methods. A primer with application to solid mechanics
Matteo Cicuttin, Alexandre Ern, Nicolas Pignet
This book is organized into eight chapters. The first three gently introduce the basic principles of hybrid high-order methods on a linear diffusion problem, the key ideas underlyi…
Spectral approximation of elliptic operators by the Hybrid High-Order method
Victor Calo, Matteo Cicuttin, Quanling Deng +1
We study the approximation of the spectrum of a second-order elliptic differential operator by the Hybrid High-Order (HHO) method. The HHO method is formulated using cell and face…
A Hybrid High-Order method for highly oscillatory elliptic problems
Matteo Cicuttin, Alexandre Ern, Simon Lemaire
We devise a Hybrid High-Order (HHO) method for highly oscillatory elliptic problems that is capable of handling general meshes. The method hinges on discrete unknowns that are poly…
Modeling of anechoich chambers with equivalent materials and equivalent sources
Silvano Chialina, Matteo Cicuttin, Lorenzo Codecasa +3
Numerical simulation of anechoic chambers is a hot topic since it can provide useful data about the performance of the EMC site. However, the mathematical nature of the problem, th…
