Hydrocode Analysis
At Shearwater we employ a wide range of cutting edge first-principle numerical tools to simulate highly dynamic events such as impact, shocks, penetration, blast, reactivity of energetic materials, and dynamic response and failure of materials. We have extensive experience using Lagrangian, Eulerian, and SPH (Smooth Particle Hydrodynamics) methods (including coupled methods) in conjunction with appropriate material models to accurately capture realistic phenomena and predict product performance.
Our team has the understanding to apply the appropriate numerical tool to the our client’s specific needs, enabling us to provide accurate and cost effective predictions in a timely manner. Shearwater personnel are experienced in using multiple codes, including: CTH, ALE3D, LS-DYNA, EPIC, SPHC, and others.
Stress Analysis
Shearwater uses LSTC LS-DYNA to perform large scale finite element analyses for rapid evaluation of mechanical stresses, strains, and deformations in component and system designs. We are skilled in using both implicit (low deformation, static and semi-static) and explicit (high deformation, high rate) numerical solvers to perform stress-strain-failure analyses.
Shearwater personnel have in-depth understanding of material behavior and apply appropriate constitutive / failure models to predict design performance. Additionally, Shearwater utilizes the Penguin-On-Demand (POD) High Performance Computing (HPC) cluster to process our computational models.
The POD provides a cost effective means to access high value computational assets, and allows for high resource availability and fast turn around times.
Engineering Model
Development and Analysis
Shearwater has a deep history developing fast-running engineering models for performing system level effectiveness evaluations. We begin the development process by leveraging high-fidelity simulations and available test data to identify key phenomena and parameters that have a first-order effect on outcomes. From this basis we develop customized analytical physics-based, empirical, and/or semi-empirical models to address the fundamentals of the problem.
Shearwater personnel have developed and implemented dozens of engineering models into parent codes for our clients. We are also skilled in using engineering models to perform broad parametric analyses to evaluate overall system performance and identify potential vulnerabilities.
Multi-Disciplinary Optimization
Shearwater utilizes the open-source DAKOTA framework developed by Sandia National Laboratories to perform Multi-Disciplinary Optimization (MDO) analyses. DAKOTA performs automated iterative analyses using a variety of gradient based, derivative-free, and global optimizations.
The DAKOTA framework can be used in conjunction with any existing model or simulation as a black box to perform optimization, parameter studies, design of experiment (DOE) analyses, uncertainty quantification, and model calibration.
Shearwater uses DAKOTA in conjunction with our high fidelity and engineering tools to provide our clients with crucial decision-making information throughout the system and/or model development processes.
