Computational Homogenization of Inelastic Materials using Model Order Reduction
(CIMNE, 2014)
The present work is concerned with the application of projection-based, model reduction techniques to the efficient solution of the cell equilibrium equation appearing in (otherwise prohibitively costly) two-scale, ...
A tool for model conversion between simulators of grid computing
(Assoc Computing Machinery, 2015-01-01)
High performance computing systems usually have a high usage cost, even with the use of shared systems, such as grids and clouds. To reduce such costs it is necessary to optimize system's utilization through performance ...
