Dear firedrakers, I would like to install firedrake on a cluster without an internet connection. Do you have any advice on how to do this? Of course, I do not have sudo privileges on the machine.

Log PETSc solver output to file
by Aaron 13 Aug '24

13 Aug '24

Dear Firedrake Team, I'm PhD student and recently started to use Firedrake for my work. I'm implementing a FEM simulation and wanted to log the convergence of the PETSc KSP solver (e.g. residuals) in a log-file for later analysis. Maybe this is trivial, but unfortunately I did not find any information in the example codes on the firedrake homepage, the mailing list and GitHub Issues/Discussions. Could you please help me with this problem? Thanks in advance. All the best, Aaron P.S. I'm working with the Firedrake Docker Image 2024-07.

Freen-Lagrange tensor
by Karin&NiKo 12 Jun '24

12 Jun '24

Dear firedrakers, I am trying to use a simple finite strain model based on the use of the Green-Lagrange tensor. Unfortunately, I get a strange error : KeyError: 'Object with key a9198fc8d1d6100862060f0212858a83 not found' Am I missing something? Everything is OK when using the linear strain tensor. The script is attached to this email. Thanks for your help, Nicolas

Firedrake installations

Dear Madam, dear Sir, I am part of the HPC platforms team and we are getting quite some tickets in regarding the installation of FireDrake. From what I understand, part of the software development is done here at Imperial as well so I thought it might be a good idea to reach out and see how we both can work together to simplify the installation of the software on HPC clusters. I am aware that other sites also have problems with users trying to install it. We are using EasyBuild here at Imperial and thus a good way forward would be to create an EasyConfig file, which will take care of all the extensions, in particular the often difficult to install PETSc one for example. Once a working EasyConfig file has been merged into EasyBuild, updating it. We done something similar with the Health-GPS project a few years ago and now that community is pushing new EasyConfig files into EasyBuild if and when there are updates of the code. If you are interested about what the EasyBuild community does, here is the program of the EasyBuild User Meeting (EUM24): https://easybuild.io/eum24/#program I am away from the University next week but happy to meet up over a coffee when I am back. Kind regards Jörg -- Dr. Jörg Saßmannshausen, MRSC (he/him) Senior Research Computing Analyst Information & Communication Technologies Imperial College London South Kensington Campus London, SW7 2AZ

AuxiliaryOperatorPC
by Cotter, Colin J 28 Apr '24

28 Apr '24

Hi folks, Has anybody tried AuxiliaryOperatorPC with coefficients dependent on the Newton state i.e. using the variable being solved for? I’m getting some quite odd behaviour (sometimes NaNs or badly solved direct solve on the PC) which I haven’t quite pinned down yet. All the best --cjc

Resource for your readers

Hi there, This is Grant again, VP of Product at Squadhelp. I reached out to you recently about your article, https://www.firedrakeproject.org/demos/DG_advection.py.html, and I think your readers will get a lot of value out of our free trademark tool https://www.squadhelp.com/check-trademark. It’s a beta tool and still needs some development to be perfect, but it’s already a great improvement on other trademark checkers out there. Why will your readers love this tool? Number one, it's completely free. Even though every use of the tool costs Squadhelp money, trademark is so important we wanted to make this powerful search available to all entrepreneurs and small business owners struggling with trademark questions. You'll also notice that the tool searches a variety of databases, not just USPTO’s TESS. So far, every trademark check runs through USPTO, Canadian trademark databases, European databases, and Australian and Canadian databases. We hope to add more in the future. Finally, Squadhelp’s trademark checker provides intelligent close-match trademarks so your users can make an informed decision about whether their name is unique enough legally, and from a marketing perspective. Would you be interested in linking Squadhelp’s Trademark Checker in https://www.firedrakeproject.org/demos/DG_advection.py.html or other content you might have on trademarks or naming? Thank you for your time, and for taking a look at the new tool. I look forward to hearing from you soon!
