An Immersed Finite Element Lagrangian-Eulerian Code-Coupling Framework

M Christon, Narendra Nanal, Chen Shen, David M. Hensinger et autres

This report presents an assessment of immersed Eulerian-Lagrangian code-coupling techniques suitable for use in a broad range of mechanics applications. The coupling algorithm is based on an immersed finite element method that considers the Lagrangian and Eulerian overlap regions in the overall …

Optimal Compressed Sensing and Reconstruction of Unstructured Mesh Datasets

Maher Salloum, Nathan Fabian, David M. Hensinger, Jina Lee et autres

Exascale computing promises quantities of data too large to efficiently store and transfer across networks in order to be able to analyze and visualize the results. We investigate compressed sensing (CS) as an in situ method to reduce the size of the …
