mumax3

Warning this is a fully compatible fork of https://github.com/mumax/3 with an added custom geometry import feature. This has been ported to the new go modules system. Needs custom build instructions, see below.

GPU accelerated micromagnetic simulator.

Tools

https://godoc.org/github.com/mumax/3/cmd

Building from source (for anything really)

• install Go
  • https://golang.org/dl/
  • set $GOPATH
• insall GIT, please
• install CUDA and nvidia driver
  • sudo apt-get install nvidia-cuda-toolkit nvidia-driver or whatever your distro does
  • only get drivers manually on windows, don't make your admin cry! https://developer.nvidia.com/cuda-downloads (pick default installation path)
  • Windows only: this project has hardcoded location for CUDA SDK to C:\CUDA, symlink/install accordingly (you need to symlink the insides of the folder with version number as the name)
• install a C compiler
  • on Ubuntu/Debian: sudo apt-get install gcc
  • on Windows either gcc or cl (from visual studio work, provided they are in PATH)
• get repo & compile
  • clone this repo git clone https://github.com/Artemkth/3.git
  • change into the repository directory
  • either a: build executable in curent dir by running go build ./cmd/mumax3 or build it into $GOPATH/bin with go install ./cmd/mumax3
  • other utilities can be built similarly by pointing at their directories instead
• optional: install gnuplot if you want pretty graphs
  • on ubuntu: sudo apt-get install gnuplot
• use the Makefile if there is a need to recompile the cuda kernels
  • make realclean && make
