Role in this project:
Back-end Developer
Back-end DeveloperContributions:216 commits, 41 PRs, 21 pushes in 6 years 8 months
Contributions summary:Kalin developed a new class, Usrbin, for parsing Fluka USRBIN output data. The initial commit created a basic structure with methods for reading data from the USRBIN file. Subsequent commits added functionality to parse Cartesian coordinate system data, extract x, y, and z coordinate information, and determine data matrix organization. Later commits implemented list data and error data to create a mesh for visualization.
