A methodology for non-Intrusive projection-based model reduction of expensive black-box PDE-based systems and application in the many-query context
… on a subspace determined via POD. However when commercial codes are used as the high-fidelity model, such an approach is not possible in general. Usually in such circumstances, a ‘POD+Interpolation’ approach is taken where the reduced state variable is directly interpolated to adapt for change …

Higher-order Petrov-Galerkin methods for analysis of antennas
… are compared with the results from two commercial codes. Mesh and time-step refinement studies are also conducted to assess the level of discretization errors in the solutions.

Finite Element Analysis of Breast Implants
… situations. The FEA work was completed using the commercial codes PATRAN and ABAQUS. PATRAN was used for pre- and post-processing, while ABAQUS was used for the actual analysis and to add fluid and contact elements not supported by PATRAN. Many different loading situations and constraints were …

Regulating sustainable development : an enabling model for consistent collaboration between planning and building control services in England
… indicate that the creation of domestic and commercial codes for sustainable development, interdisciplinary undergraduate educational initiatives and performance driven regulatory social enterprise offer the potential to address existing field based problems. In addition, evidence suggests …

Development and implementation of robust large deformation and contact mechanics capabilities in process modelling of composites
… other experiments and the same models in other commercial codes. Finally, several interesting cases are examined to explore the results of COMPRO predictions with the added options.

Numerical Evaluation Of Different Retrofitting Techniques Of New Orleans Floodwalls And Implementation Of Advanced Constitutive Model In Flac3D
… analysis as they are not readily available in commercial codes. So, to fill this gap, as a second objective, this study implemented the new user defined constitutive model (Anisotropic Modified Cam Clay Model) in FLAC3D, by taking the advantage of user defined model capability. The implemented …

AN IMPROVED ROCK MASS BEHAVIOR NUMERICAL MODEL AND ITS APPLICATIONS TO LONGWALL COAL MINING
… behavior using FLAC3D numerical code (most commercial codes do not have a built in model for gob material) and its effects on load transfer into gate entries, 3) Identify mechanisms of instability in setup rooms, 4) Develop alternate 3- and 4-entry set-up room geometries using 3-D numerical …

Development and modelling of new wideband microstrip patch antennas with capacitive feed probes
… but extremely difficult to analyse with commercially available software. Probe-fed microstrip patch antennas have always been a popular candidate for a variety of antenna systems. Due to their many salient features, they are well suited for modern wireless communication systems. However, …

Efektivita zajištění závazků
Tématem diplomové práce je efektivita zajištění závazků, cílem je nastínit přehled základních zajišťovacích institutů v obecné rovině, které český právní řád v současné době nabízí a pokusit se nalézt ten nejefektivnější. V teoretické části se zaměřuji na závazkové vztahy, jejich druhy a důvody …

Implementation and Validation of the ζ-F and ASBM Turbulence Models
… Due to their wide range of use, industrial CFD codes are becoming more flexible and easier to use. These commercial codes require robustness, reliability, and efficiency. Consequently, linear eddy viscosity models (LEVM) are used to model turbulence for an increasing number of flow types. LEVM …

Resource Allocation on Networks: Nested Event Tree Optimization, Network Interdiction, and Game Theoretic Methods
… ingredients, including comparisons with the commercial software BARON. The developed set of algorithmic implementation strategies and enhancements are shown to outperform BARON over a set of simulated test instances, where the best proposed methodology produces an average optimality gap of …
