Dear all, This week's FEM lecture will be on Friday from 1030-1200 in WPL3.01 as usual. This week we'll be venturing out into the world of FEM in more than one dimension!

cvxgen
by Kelly, Paul H J 29 Jan '14

Francis and I just came across this: http://cvxgen.com/docs/index.html "CVXGEN generates fast custom code for small, QP-representable convex optimization problems, using an online interface with no software installation. With minimal effort, turn a mathematical problem description into a high speed solver." Firstly, more fellow-travellers in the DSLs for computational science space. Secondly, potentially applicable in vision stuff, maybe. Paul

Re: [firedrake] Boundary condition docs (#152)

From the manual: http://www.firedrakeproject.org/variational-problems.html?highlight=extrude… We may also build square meshes with the UnitSquareMesh <http://www.firedrakeproject.org/firedrake.html#firedrake.mesh.UnitSquareMesh> constructor, and cube meshes with UnitTetrahedronMesh <http://www.firedrakeproject.org/firedrake.html#firedrake.mesh.UnitTetrahedr…>. Tetrahedron or cube? --cjc

Re: [firedrake] pyOP2 installation

This is correct. Installing PETSc via PiP will install PETSc in the Python subtree. It won't go anywhere near your system PETSc installation.

Paper from the Deal.II people on something vaguely OP2-like
by David Ham 28 Jan '14

28 Jan '14

Hi All, The Deal.II people have put a submitted preprint of something which looks a little OP2-like up on the web. http://www.math.tamu.edu/~bangerth/publications/2013-pattern.pdf They cite some of our earlier work (although I think they mischaracterise it fairly awfully), but they don't mention PyOP2, which is unfortunate.

pyOP2 installation
by Colin Cotter 28 Jan '14

28 Jan '14

Dear firedrakers, I'm going to attempt a pyOP2 installation this evening. As I've already mentioned to David and Lawrence, I'm concerned about breaking my build for our quads Fluidity branch which requires Petsc 3.1, which I currently bring in via an environment module. Do I correctly understand that if I pip install the python Petsc 3.4 module that this will be installed somewhere else and won't cause me any bother when I try to use the quads branch? Please reassure me and let me know if I have to do something other than what is written on the pyOP2 installation page in order to get this right. all the best --Colin

FEM course recommences 1030 23 January
by David Ham 22 Jan '14

22 Jan '14

Hello all, For those who have been following the FEM course in person or online, we will start again next Thursday at 1030. I plan to cover the construction of basis functions in preparation for moving on to FEM in more dimensions the following week. As usual, the videos will appear online as soon as they are processed, which will probably be the day after they are given. Links to the videos so far can be found at http://wp.doc.ic.ac.uk/spo/finite-element/ Regards, David -- Dr David Ham Departments of Mathematics and Computing Imperial College London http://www.imperial.ac.uk/people/david.ham
