Achievements

Updated proposal and JOOMMF work plan to reflect the removal of WP7
T2.7 Open source dissemination of micromagnetic VRE
- Repositories for source code under github.com/joommf
- Set up publicly accessible Jenkins/Travis CI to
- Added Docker image containing JOOMMF and all its dependencies to DockerHub
- Another announcement made to the community via micromagnetic mailing list
- Conda installation developed 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
- Some unresolved problems with conda installation of OOMMF on Windows
T2.8 Micromagnetic VRE dissemination workshops
- Three workshops completed
- Two workshops/tutorials scheduled
- Publications, conference contributions, and tutorials listed in the “Other” section.
- Details in the “Workshops and dissemination activities” 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)
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
T2.7: conda package for windows

Workshops and dissemination activities

Three workshops have been completed in this period:

Institute of Physics (IOP) Magnetism conference, 04 April 2017, York, UK
- details about the workshop here
- about 30 participants
- organisers did not allow us to have the details of registered participants due to data protection
- 19 participants provided their details directly to us: 6 females, 13 males
- Workshop conducted jointly with Michael Donahue - developer of OOMMF
- Workshop materials (tutorials and exercises) are available here
- Co-funded with EPSRC CCP Computational Magnetism Network (EP/M022668/1)
Intermag 2017 conference, 24 April 2017, Dublin, Ireland
- One of the major conferences in the field of magnetism research
- 50 registered participants, plus 7 additional attendees
- Two sessions: main workshop event and the follow up session
- The follow up session was used to go into more details about specific features of JOOMMF and to receive feedback and requests from users
- Co-funded with EPSRC CCP Computational Magnetism Network (EP/M022668/1)
62nd Annual Conference on Magnetism and Magnetic Materials, 06-10 Nov 2017, Pittsburgh, PA, USA
- One of the major conferences in the field of magnetism research
- Workshop conducted informally with JOOMMF users and people who want to start using it
- Received feedback from the users as well as the feature requests

One tutorial has been scheduled for the upcoming period:

Advances in Magnetism 2017, 04-07 February 2018, La Thuile, Italy
- Tutorial session for all conference attendees
