8:00 AM – 12:00 PM: Building Better Scientific Software

Presented by Kyle Niemeyer

Department of Mechanical, Industrial, and Manufacturing Engineering, Oregon State University

This workshop will dive into best practices for developing research software, and sharing artifacts of research openly. Topics include version control with Git, working collaboratively with GitHub, software testing and continuous integration, effectively documenting software, deploying and sharing software openly, software licenses and copyright, and writing and publishing about software, including software citation. Each topic will be fairly interactive and hands-on, and participants will follow along on their laptops


1:00 PM – 5:00 PM: Response Matrix Theory of 1D Neutron Transport in Plane Geometry

S. Chandrasekhar is widely credited with the development of the first solutions to the 1D radiative transfer equation falling into the category of response matrix or nodal-like methods. In particular, a set of ODEs at quadrature abscissae approximates the radiative or neutron transport equation. A solution in terms of exponential eigenfunctions then immediately follows. C. Siewert, R. Garcia, L. Barichello and co-workers have perfected the method by using modern day methods of numerical linear algebra. In addition, there have been many researchers including B. Carlson, E. Gelbard, J. Lenoble, S. Segatto, K. Stamnes and W. Wiscombe to name a few, who have modified Chandrasekhar’s method and expanded the number of applications. In this Workshop, we explore a recently established alternative numerical solution called the Response Matrix/Discrete Ordinates Method (RM/DOM) which enables the generation of high precision 1D benchmarks. I will present the theory, based on the SN equations, along with its numerical implementation. Coupling RM/DOM to the method of doubling provides a range of highly precise solutions for both large and small slabs in heterogeneous media. During the presentation, several short specially prepared exercises in MATLAB are given to demonstrate the numerical methods used. Graduate students, professors and those generally interested in learning more about precision transport theory will find the Workshop helpful for code verification. Participants attending will receive a memento to remember their Workshop experience. The duration is four hours with refreshments provided.

There is no charge for either of these workshops. However, please send us an email to let us know if you plan on attending, and which workshop(s) you would like to participate it. Due to logistics and space limitations each workshop will be limited to the first 30 respondees.  

On behalf of the 2019 International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2019), The Mathematics and Computation Division (MCD) of the American Nuclear Society would like to formally invite you to attend the Eli Gelbard Scholarship fundraising event on Tuesday evening, August 27, 2019. The event will be held in the beautiful city of Portland, Oregon, aboard the Crystal Dolphin Vessel. Guests will enjoy a 2.5-hour yacht cruise down the Willamette River while enjoying amazing views and a locally sourced and freshly prepared northwestern cuisine. Your $60.00 donation will include the cruise, a three-course meal, and beverages (alcoholic & non-alcoholic).


Ely Gelbard was a distinguished long-time member of the Mathematics and Computation Division (MCD) and after his death in 2002, the MCD voted to establish a graduate scholarship in his honor. The Eli Gelbard scholarship is offered to full-time students pursuing graduate studies with a focus on the development of mathematical and/or computational methods for nuclear applications. The MCD is committed to contributing approximately one-third of the money required to fund the scholarship from their operating funds, but we need your help raising the remaining two-thirds, so donations over the initial requested amount are welcome.
