Grain growth model in APL

Dyalog APL script to perform grain growth simulations. The model is a slightly simplified version of:

• Traka 2022

Installation

Download and extract into some directory.

Usage

First, make sure Dyalog version 18.2 or higher is installed, and set the simulation parameters editing the gg.json file (the comments in the file explain the meaning of each parameter). Then, run the gg.apls script on a command window or double-click the corresponding icon.

Alternatively, from the Dyalog interpreter:

2⎕FIX{⍵⌿⍨(' '=⊃¨⍵)∨':{}'∘(∨/∊)¨⍵}⊃⎕NGET'gg.apls'1
Sim'gg.json5'

Plotting

The script 'plotgg.m' can be used to plot the initial and final microstructures with MTEX. Eg:

plotgg('./gg_')
