$\texttt{cuSkyrmion}$: A CUDA-OpenGL framework for interactive simulation and visualization of nuclei as Skyrmions

Abstract

We introduce $\texttt{cuSkyrmion}$, a 3-dimensional Skyrme model computation and visualization software, that is written in $\texttt{CUDA C}$ for rapid computation and visualization of especially the arrested Newton flow algorithm. The programme is interactive and lets the user construct Skyrmions either with configuration files, specifying coordinates, or simply in run-time using the keyboard and mouse. Rational map ansatz constituent Skyrmions can be inserted at any time and a random generator can produce a stochastic initial configuration. The software is composed into three main modules being a computational module, a rendering module and a main programme. The rendering/visualization module can readily be used by other computational modules and a $\texttt{Python}$-fork, $\texttt{skyrmion_solver}$, has been developed demonstrating the re-usability of the code.
