Unified Framework for Finite Element Assembly
, 2009 At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs.

Energy-corrected FEM and explicit time-stepping for parabolic problems
, 2019 The presence of corners in the computational domain, in general, reduces the regularity of solutions of parabolic problems and diminishes the convergence properties of the finite element approximation introducing a so-called "pollution effect".

A Hybrid High-Order method for Leray-Lions elliptic equations on general meshes
, 2016 In this work, we develop and analyze a Hybrid High-Order (HHO) method for steady non-linear Leray-Lions problems. The proposed method has several assets, including the support for arbitrary approximation orders and general polytopal meshes.

A combined finite-discrete element method for simulating pharmaceutical powder tableting
International Journal for Numerical Methods in Engineering, 2005 Summary: The pharmaceutical powder and tableting process is simulated using a combined finite-discrete element method and contact dynamics for irregular-shaped particles. The particle-scale formulation and two-stage contact detection algorithm which has been developed for the proposed method enhances the overall calculation efficiency for particle ...
