Dear friends and colleagues, It is a great pleasure to announce the PDE Software Frameworks (PDESoft) 2018 Conference, which will be held at the hotel Zander K (https://www.zanderk.no/en/) Bergen, Norway, May 28 - 30, 2018. The scientific committee of the conference consists of the following people: - Donna Calhoun (Boise State University) - Lois Curfman McInnes (Argonne National Laboratory) - Guido Kanschat (Heidelberg University) - Eirik Keilegavlen (University of Bergen) - Robert Klöfkorn (International Research Institute of Stavanger) - Lawrence Mitchell (Imperial College London) - Christophe Prud'homme (University of Strasbourg) - Garth Wells (University of Cambridge) - Barbara Wohlmuth (Technical University of Munich) We welcome abstracts on topics related to software for - meshing and adaptive mesh refinement, - solvers for large systems of equations, - numerical PDE solvers, - data visualization systems, - user interfaces to scientific software, and - reproducible science. The accepted abstracts will be scheduled for either oral or poster presentations. This workshop does not publish full papers, so submission of a full paper is not required. The deadline for abstract submission is Feb. 1, 2018. For more information, please see the PDESoft18 web page: http://www.iris.no/pdesoft18/. We are looking forward to meeting you in Bergen.

Firedrake in the Classroom
by Francis Poulin 14 Dec '17

14 Dec '17

Hello everyone, In January I start teaching an introductory course in PDEs. I have taught this many times but this time I plan to have a weekly computer lab where the students can learn to run software (based on firedrake) and then write a lab report. I have a bunch of notebooks that I will give to them one at a time and get them to solve a variety of problems. Before I do I have a few questions. * I presume no one has a problem with this? * There are 40 some students registered in the class. I don't plan to get them to change the code except for parameters and maybe functions. But if students have questions they can go through the usual channels to ask questions, i.e. email and slack? * I know that it is good practice for each firedraker to install their own code but I am going to install it on a server and let them use it, since it will be so much easier for them. If you have any warning as to what might go wrong please let me know. * If it would be helpful to advertise somewhere that I am using firedrake in a course, please let me know how. Cheers, Francis ------------------ Francis Poulin Associate Dean, Undergraduate Studies Associate Professor Department of Applied Mathematics University of Waterloo email: fpoulin(a)uwaterloo.ca Web: https://uwaterloo.ca/poulin-research-group/ Telephone: +1 519 888 4567 x32637

Hello, I recently had to reinstall firedrake, which went well, but then when I tried installing slepc using "firedrake-update --slepc" I got the following error. I am including the log file. Any idea what might be the problem? Cheers, Francis Failed to clone slepc using ssh, falling back to https. Successfully cloned repository slepc.

Dear Firedrakers, The Firedrake team will be running a half day tutorial introducing the use of Firedrake to solve PDEs using the finite element method. This is primarily targeted at new students starting to work with Firedrake this academic year, but anyone is welcome. If you have any new users in your group or know anyone who might be interested, please point them at this event. Attendance is free but registration is required. For more information and to register, visit the tutorial web page: http://www.firedrakeproject.org/tutorial_jan_18.html Regards, David
