Scalable hierarchical PDE sampler for generating spatially correlated random fields using non-matching meshes
Sarah Osborn, Patrick Zulian, Thomas Benson +3
This work describes a domain embedding technique between two non-matching meshes used for generating realizations of spatially correlated random fields with applications to large-s…
The auxiliary space preconditioner for the de Rham complex
Jay Gopalakrishnan, Martin Neumüller, Panayot Vassilevski
We generalize the construction and analysis of auxiliary space preconditioners to the n-dimensional finite element subcomplex of the de Rham complex. These preconditioners are base…
A Multilevel, Hierarchical Sampling Technique for Spatially Correlated Random Fields
Sarah Osborn, Panayot Vassilevski, Umberto Villa
We propose an alternative method to generate samples of a spatially correlated random field with applications to large-scale problems for forward propagation of uncertainty. A clas…
