bigquantum / yolohtli

Yolohtli is a 2D cardiac electrophysiology solver developed in C/CUDA parallel programming language. The solver has many functionalities to facilitate the user experience and analysis. These include easy to use loading/saving options, keyboard/mouse user interactivity, and real time OpenGL graphics. Moreover, several non-standard functions have been implemented to monitor the evolution of spatio-temporal patterns, such as spiral tip tracking, contour tracking, complex boundaries, external stimulation, and many more.

Yolohtli

A cardiac electrophysiology partial differential equation solver

This software is a numeric PDE solver for ionic cardiac models in 2D with real-time graphics. The program has two main solver modes: standard PDE solver, and symmetry-reduction solver for spiral waves.
