Neurite is a program with wich the simulations shown in the paper J.A. Garcia-Grajales, G. Rucabado, A. Garcia-Dopico, J.M. Pena and A. Jerusalem, "Neurite, a finite difference large scale parallel program for the simulation of the electrical signal propagation in neurites under mechanical loading", García-Grajales JA, Rucabado G, García-Dopico A, Peña J-M, Jérusalem A (2015), PLoS ONE 10(2): e0116532. doi:10.1371/journal.pone.0116532, have been carried out. Neurite is a finite difference program that simulates the electrical signal propagation in myelinated and unmyelinated axons, and in dendritic trees under mechanical loading. The program has two different solvers---explicit and implicit---that can be executed sequentially with a CPU processor or in parallel with GPU accelerators. To compile the code in UNIX system, type "make" in the root directory (see in the Makefile for more compiling options). To execute a simulation, go in the applications folder and follow the Readme.
