Fun fact?
In the 1950s–60s, the Polaris missile program (submarine-launched ballistic missiles, first (PC) computers), the adjoint method was used for optimal control—the same method later branded as backpropagation, now honoured with a Nobel Prize.

Seeking robustness while preserving high accuracy is a tricky business. We are on the right track, but not yet where I would like us to be. We are testing the Higham method for projecting onto a cone of symmetric positive-definite matrices.

In #MoFEM (mofem.eng.gla.ac.uk), we like to break things and are not bad at this.

Today was perfect weather for a swim in Loch Lomond. It was my second time, but I am already addicted to open water swimming.

First MoFEM work in Ukrainian on a block solver for GPU. :)

Interesting discussions on HPC, AI, and computing. From my perspective, we often solve not the problems we want, but the ones we can. Also, it makes no sense to build infrastructure solely for AI; the same infrastructure can be used for other things.

We have the pleasure of running a workshop on modelling cracks in MoFEM for our colleagues from EDF and Amentum from 8 to 9 May. We have been working together on this topic for over 16 years.

MoFEM accoring OpenHub. There are 53 developers, but according to the estimate, it will take a single professional programmer 73 years to write our code!

Let's pray, mechanics. Mechanics have one dogma, and that is objectivity.

BTW Bandwith for L2 and H-div can be a priori determined, and does not depend on the mesh. Made in #MoFEM
Energetic spaces. The same mesh, 4th order, different space. You can observe how space (not the base itself) renders matrix structure and sparsity.

Putin wanted to stop NATO from expanding, and it ended up with Sweden and Finland joining it. It would be funny if Trump wanted to annex Canada, and it ended up joining the EU.

Multibody contact with our hybridised solver. In Blender, I learned to handle multiple components and move the camera along the path. The effect is moderate.
