• T2.7 Open source dissemination of micromagnetic VRE
  • Repositories for source code under github.com/joommf
  • Set up publicly accessible Jenkins/Travis CI
  • Added Docker image containing JOOMMF and all its dependencies to DockerHub
  • Another announcement made to the community via micromagnetic mailing list
  • Conda installation done for OOMMF and all JOOMMF packages (OSX and Linux)
  • Set up read the docs for every code repository
  • Set up code coverage for all code repositories

• T2.8 Micromagnetic VRE dissemination workshops
  • Workshops
    • Five workshops completed
    • One workshop (walk-in session) scheduled in Washington DC, USA in January 2019
    • Details in the “Workshops and dissemination activities” section
  • Publications, conference contributions, and tutorials listed in the “Other” section.
• T4.14 Online portal for Micromagnetic VRE demonstrator
  • No separate machine was purchased to host it; using existing hardware at University of Southampton instead (courtesy of EPSRC Center for Doctoral Training in Next Generation Computational Modelling)
  • Online portal is based on Docker and provides the anonymous use of JOOMMF
  • Available here
  • Allows users to re-execute the tutorial and documentation notebooks
  • It will develop over time as further extensions to JOOMMF are made (T3.8 and T4.11) and more tutorial notebooks written (T4.13)
  • We also employ MyBinder for running JOOMMF in the cloud
  • We also have an intentyion to use EGI
• T4.13 Demonstrator: MVRE notebooks
  • Jupyter notebooks documenting specific features of JOOMMF
  • Tutorials used for workshops (here)

Work in progress

• Further work and extensions in all work packages.

• T3.8: Further developments and extensions (OOMMF Python interface)

• T4.9 & T4.11: 3d visualisations of vector fields, and widgets
