# MuMax3-How-To
[](https://choosealicense.com/licenses/gpl-3.0/)
Installation, scripting, & data generation demo of computational micro and nanomagnetism in MuMax3. Formed & written by Onri Jay Benally, an Indigenous American quantum hardware engineer.
______________________________________________________________________________________________________________________________________________________
______________________________________________________________________________________________________________________________________________________
Uses code heavily-modified for clarity, inspired from: (https://github.com/mumax/3) & (https://mumax.github.io/examples.html)
(Examples computed in this repository were performed on an NVIDIA (RTX4070 Ti Super) GPU, connected externally to a Microsoft Surface Pro 8).

## If MuMax3 is installed already, start the GUI by typing the following 2 lines into a non-admin command prompt or non-admin PowerShell:
```bash
cd <directory_to_your_MuMax3_file>
```
```bash
mumax3 -i <your_MuMax3_TXT_file_name>
```
Note: MuMax3 scripts can be written as TXT file types. The above script will load and automatically run the script into a browser.
Online OVF file type visualization: (https://mumax.ugent.be/mumax-view). While using the viewer, you can load multiple OVF files to play an animation of the magnetization frame capture.
