Conservative model reduction for finite-volume models
, 2018 This work proposes a method for model reduction of finite-volume models that guarantees the resulting reduced-order model is conservative, thereby preserving the structure intrinsic to finite-volume discretizations.

Space-time discontinuous Galerkin method for the compressible Navier-Stokes equations on deforming meshes [PDF]
, 2006 An overview is given of a space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations. This method is well suited for problems with moving (free) boundaries which require the use of deforming elements. In addition,

Large deformation analysis of elastic bodies by nonlinear Petrov–Galerkin natural element method
Advances in Mechanical Engineering, 2019 A two-dimensional nonlinear Petrov–Galerkin natural element method is presented for the large deformation analysis of elastic structures. The large deformation problem is formulated according to the linearized total Lagrangian method based on Taylor ...

A convergent nonconforming finite element method for compressible Stokes flow [PDF]
, 2009 We propose a nonconforming finite element method for isentropic viscous gas flow in situations where convective effects may be neglected. We approximate the continuity equation by a piecewise constant discontinuous Galerkin method. The velocity (momentum)
