Performance Evaluation of ANCF Tetrahedral Elements in the Analysis of Liquid Sloshing
(The American Society of Mechanical Engineers (ASME), 2020)The performance of the absolute nodal coordinate formulation (ANCF) tetrahedral element in the analysis of liquid sloshing is evaluated in this paper using a total Lagrangian nonincremental solution procedure. In this ... -
Progress Toward a Complete Set of Errors for Modeling and Simulation
(The American Society of Mechanical Engineers (ASME), 2020)To develop a fully complete set of errors associated with modeling and simulation, it is necessary to express every error that could impact the accuracy of a computational model's prediction of the real world system (i.e., ... -
Predictive Capability Maturity Quantification Using Bayesian Network

Quantifying Uncertainty in Warhead Design: How Machining Uncertainty Affects Weight and Center of Mass
(The American Society of Mechanical Engineers (ASME), 2020)In this work, we explore how uncertainty in component dimensions affects final product tolerances for warheads. We focus on quantifying uncertainties arising from the machining process and examine how they influence the ... -
Local Truncation Error-Informed Code Verification
(The American Society of Mechanical Engineers (ASME), 2020)The method of manufactured solutions (MMS) has become increasingly popular in conducting code verification studies on predictive codes, such as nuclear power system codes and computational fluid dynamic codes. The reason ... -
Multi-Element Stochastic Galerkin Method Based on Edge Detection for Uncertainty Quantification of Discontinuous Responses
(The American Society of Mechanical Engineers (ASME), 2020)We propose a new multi-element generalized polynomial chaos (MEgPC) method to minimize the computational costs required for the existing MEgPC to circumvent the Gibbs phenomenon in the presence of discontinuities in a ... -
Truncation Error Based Mesh Optimization
(The American Society of Mechanical Engineers (ASME), 2020)Truncation error is used to drive mesh adaptation in order to reduce the discretization error in solutions to a variety of 1D and 2D flow problems. The adaptation is performed using r-adaptation to move the mesh nodes in ... -
Construction of a Code Verification Matrix for Heat Conduction With Finite Element Code Applications
(The American Society of Mechanical Engineers (ASME), 2020)When establishing the pedigree of a simulation tool, code verification is used to ensure that the implemented numerical algorithm is a faithful representation of its underlying mathematical model. During this process, ... -
Code Verification of a Pressure-Based Solver for Subsonic Compressible Flows
(The American Society of Mechanical Engineers (ASME), 2020)Although most flows in maritime applications can be modeled as incompressible, for certain phenomena like sloshing, slamming, and cavitation, this approximation falls short. For these events, it is necessary to consider ... -
