Error estimation and control are critical ingredients for improving the reliability of
computational simulations. Adjoint-based techniques can be used to both estimate the error …

In the context of scientific computing, the mesh is used as a discrete support for the
considered numerical methods. As a consequence, the mesh greatly impacts the efficiency …

An improvement to the classical finite element (FE) method is proposed. It is able to exactly
represent the geometry by means of the usual CAD description of the boundary with non …

This paper presents a technique that allows to untangle high-order/curvilinear meshes. The
technique makes use of unconstrained optimization where element Jacobians are …

The field of mesh generation concerns the development of efficient algorithmic techniques to
construct high-quality tessellations of complex geometrical objects. In this thesis, I …

A procedure for generating curved meshes, suitable for high-order finite element analysis, is
described. The strategy adopted is based upon curving a generated initial mesh with planar …

Large eddy simulation (LES) has been shown to be very promising in computing vortex-
dominated turbulent flows. The proliferation of high-order methods capable of handling …

We present a method for the generation of higher-order tetrahedral meshes. In contrast to
previous methods, the curved tetrahedral elements are guaranteed to be free of …

We propose a method to generate high-order unstructured curved meshes using the
classical Winslow equations. We start with an initial straight-sided mesh in a reference …

We present a successful deployment of high-fidelity large-eddy simulation (LES)
technologies based on spectral/hp element methods to industrial flow problems, which are …
