Monthly CIRC Symposia
Every third Friday of the month, the Center for Integrated Research Computing hosts a research symposium (known as the CIRC Symposium), where faculty, staff, and student researchers convene to learn about research projects utilizing the center’s resources, meet potential collaborators, and learn about new technologies and trends in research computing. This event is user-driven and features presentations by researchers using CIRC systems. CIRC Symposia are open to all members of the university community.
The Center for Integrated Research Computing (CIRC) will host its next symposium on Friday, January 16th 11:30 am – 1 pm in Wegmans Hall 1400
This month’s featured speaker is Duc Cao from the Laboratory for Laser Energetics. Duc will demonstrate computational models of hydrodynamic instability in direct-drive fusion targets.
The ongoing research talk will be given by Aditya Ranjan from the Department of Mechanical Engineering. Aditya will show how computational fluid dynamics simulations can be used to estimate the permeability of brain tissue.
Modeling Hydrodynamic Instability Growth in Direct-Drive Fusion Targets with Embedded Tracer Layers
Duc Cao, PhD
Laboratory for Laser Energetics
In direct-drive inertial confinement fusion (ICF) implosions, lasers uniformly illuminate a spherical target, compressing it to pressures and temperatures exceeding those at the center of the Sun to achieve nuclear fusion. The energy yield, directly linked to neutron production, is influenced by the symmetry of the compression, which can be disrupted by Rayleigh-Taylor hydrodynamic instabilities. These instabilities arise from asymmetries in laser illumination (notably laser imprinting from speckle) or target imperfections. This study presents high- fidelity simulations designed to evaluate the growth of hydrodynamic instabilities in a representative ICF target. The target also incorporates a mid-Z tracer layer, which serves as a diagnostic marker to
track the penetration depth of instabilities during the implosion. Simulated emission signatures from the tracer layer over time provide a framework for comparison with experimental data to assess discrepancies between modeled and observed instability growth. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number(s) DENA0004144.
Estimating the Permeability of Brain Tissue through CFD Simulations of Flow in Realistic Geometries
Aditya Ranjan
Department of Mechanical Engineering
Cerebrospinal fluid flows into the brain tissue and clears metabolic waste products, a critical process for preventing neurological diseases like Alzheimer’s. Hence, understanding the role of fluid flow in maintaining brain health is of critical importance, but fluid flow within the brain tissue cannot be directly measured, leaving many open questions. In our study, we estimate the permeability of brain tissue using computational fluid dynamics simulations of flow through a realistic three-dimensional ECS geometry derived from publicly available data. We solved for the speeds resulting from an imposed pressure drop in Stokes flow since ECS flow is characterized by very low Reynolds numbers and then calculated the permeability using Darcy’s law.
Information about previous CIRC Symposia is available.
CIRC Summer School
Every summer, CIRC hosts a four-week training session on various operating systems, programming languages, computational programs and libraries, and data analytics tools for the research community. Known as the “CIRC Summer School,” these workshops are broken down into individual topics and feature small, interactive, classroom-based instruction sessions. Topics range from basic training in Linux to optimizing codes for parallel computing. The courses are designed for beginner and advanced users alike. Extra emphasis is placed on using the various available languages, libraries, etc., specifically on BlueHive.
CIRC Winter Boot Camp
Have you ever wanted to learn how to program or add a new programming language to your existing knowledge? Have you been looking for the right time to pick up a few essential technical computing skills to help with your research projects or course work? Well, now you have the opportunity during the CIRC Winter Boot Camp!
The Center for Integrated Research Computing (CIRC) hosts a multi-week winter program to help students, postdocs, research staff, and faculty learn new programming languages and sharpen their computing and data analytics skills. The classes are designed for beginners and cover basic topics to give enough direction to move on to self-learning tutorials or other more advanced coursework.
Check again soon for an announcement about the next Winter Bootcamp!
CIRC Workshops
The Center for Integrated Research Computing (CIRC) offers workshops every Spring and Fall that introduce users to the BlueHive computing environment and other computing resources that CIRC supports. The workshops include sessions in the morning targeted for new and beginning users, and afternoon sessions covering a few more in-depth topics and tools and applications that are available to the research community.
Annual CIRC Poster Session
The Center for Integrated Research Computing holds the Annual CIRC Poster Session at the end of each Spring semester. At this event, attendees discover the wide range of research that is enabled by computation and displayed to the University community. This event provides an informal venue to share computational and data analytics techniques and methodologies with colleagues from a wide variety of disciplines.
