An algorithm for isometrically embedding curvilinear meshes defined on Riemannian metric spaces into Euclidean spaces of sufficiently high dimension is presented. The method is derived from the Landmark-Isomap algorithm and a previous method for embe

Adaptive Characteristic Length for L-SIAC Filtering of FEM Data

Autor: Robert Haimes, Ashok Jallepalli, Robert M. Kirby

Publikováno v: Journal of Scientific Computing. 79:542-563

Treating discontinuities at element boundaries is a significant problem in understanding high-order FEM simulation data since the physics used to model the simulation is often continuous. Recently, the family of SIAC filters, especially the L-SIAC fi

On the Treatment of Field Quantities and Elemental Continuity in FEM Solutions

Autor: Julia Docampo-Sanchez, Robert M. Kirby, Jennifer K. Ryan, Ashok Jallepalli, Robert Haimes

Publikováno v: IEEE Transactions on Visualization and Computer Graphics. 24:903-912

As the finite element method (FEM) and the finite volume method (FVM), both traditional and high-order variants, continue their proliferation into various applied engineering disciplines, it is important that the visualization techniques and correspo

Anisotropic geometry-conforming d -simplicial meshing via isometric embeddings

Autor: Philip Claude Caplan, Marshall C. Galbraith, David L. Darmofal, Robert Haimes

Publikováno v: Elsevier

We develop a dimension-independent, Delaunay-based anisotropic mesh generation algorithm suitable for integration with adaptive numerical solvers. As such, the mesh produced by our algorithm conforms to an anisotropic metric prescribed by the solver

Publikováno v: AIAA Aviation 2019 Forum.

The quantification and control of discretization error is critical to obtaining reliable simulation results. Adaptive mesh techniques have the potential to automate discretization error control, but have made limited impact on production analysis wor
