In this repository you can find the code files that are part of the work: "Eckhaus selection: The mechanism of pattern persistence in reaction-diffusion systems" Aldo Ledesma, Alejandra Ortiz, Jodé Luis Aragón e Iván Santamaría.
-
The Comsol file (.mph) "simulations" contains the solution for the Bruselator system, a reaction-difussion system, that will be used in all programs.
-
The Mathematica (.nb) files that allow the Fourier Analysis are arranged in each folder of numerical solutions in the same order that they appear in the article.
-
Inside each folder there is a readme.txt file that details how each calculation was made.
-
All Mathematica and Comsol files are also commented inside describing the steps of calculations.
-
Comsol 5.2 and Mathematica 11 were used for the final versions of these files.
