The Laboratoire National des Champs Magnétiques Intenses (LNCMI) is a French large scale facility enabling researchers to perform experiments in the highest possible magnetic field. DC magnetic fields up to 36 T are provided at the Grenoble site and pulsed fields up to 99 T at Toulouse. The technology used for DC magnets relies on the so-called polyhelix inserts for the most stressed parts of the magnets. Their design relies on non-linear 3D multi-physic models.
HiFiMagnet is a research project carried out by the LNCMI in collaboration with Institut de Recherche Mathématique Avanc'ee (IRMA) and Cemosis.
The goals are twofold:
-
to build a hierarchy of numerical models ranging from 2D axi to 3D, and including more and more physics. The idea here is to reconsider the hypothesis that are needed to derive the semi-analytical approximations upon which our standard design and optimization procedures are based and ultimately to quantify the hypotheses effects;
-
to complement our standard design by performing sensitivity analysis and uncertainty quantification on material properties, operational parameters and geometric clearances. It allows e.g. to identify the important parameters, to perform quantile estimation, to compute probability of failure and ultimately to provide safety operational controls.
Models have been implemented with the finite element library Feel++.
We’re always happy to help out with HiFiMagnet or any other questions you might have. You can ask a question or signal an issue at the Gitter HiFiMagnet salon.
You can contribute to improve this documentation on GitHub and follow the Gitter HiFiMagnet Book forum.
You only require an node >= 8 install.
make install
make build
make serve|
Note
|
This will install antora. Then compile the book. And finally run a local web server to visualize the documentation in a web browser: |
firefox http://localhost:8000/Alternatively you can run the book within a docker container:
docker pull antora/antora:2.2.0Then simply start the docker image:
docker run -it --rm --entrypoint ash -v `pwd`:/antora/hifimagnet -v $HOME/book.feelpp.org:/antora/book.feelpp.org -p 80:8080 antora/antora:latestthe pwd shall be the source dir of the book and $HOME/book.feelpp.org the source dir of feelpp book.
Then in the container:
cd hifimagnet
antora antora-local-feelpp-doc.ymlTo start and serve the documentation:
npm i -g live-server
live-server build/siteTo view the documentation in a web browser, this time you will simply:
firefox http://localhost/If the host is accessible from internet (and the port 80 is open), you can also access the documentation from any place:
firefox http://host_ip/|
Tip
|
this won’t work if any http server is already running on port 80 on you host_ip.
Make sure to shutdown the http server before running the above commands.
|
|
Tip
|
you can use nmap -p 80 host_ip to check if http port is open on host_ip
