h-multigrid agglomeration based solution strategies for discontinuous Galerkin discretizations of incompressible flow problems [PDF]
, 2017 In this work we exploit agglomeration based $h$-multigrid preconditioners to speed-up the iterative solution of discontinuous Galerkin discretizations of the Stokes and Navier-Stokes equations.

Effects of Mesh Generation on Modelling Aluminium Anode Baking Furnaces
Fluids, 2021 Anode baking is critical in carbon anode production for aluminium extraction. Operational and geometrical parameters have a direct impact on the performance of anode baking furnaces (ABF), and hence on the resulting anode quality.

Plume spreading test case for coastal ocean models [PDF]
Geoscientific Model Development, 2021 We present a test case of river plume spreading to evaluate numerical methods used in coastal ocean modeling. It includes an estuary–shelf system whose dynamics combine nonlinear flow regimes with sharp frontal boundaries and linear regimes with cross ...

Parameterization of Quadrilateral Meshes [PDF]
, 2007 Low-distortion parameterization of 3D meshes is a fundamental problem in computer graphics. Several widely used approaches have been presented for triangular meshes. But no direct parameterization techniques are available for quadrilateral meshes yet.

Boundary Deformation Measurement by Mesh-Based Digital Image Correlation Method
Applied Sciences, 2020 Digital image correlation (DIC) is a popular photomechanics method for deformation measurement. The conventional subset-based DIC method obtains the displacement vectors at the subset centers, but cannot calculate the deformation on the specimen edges ...
