God made the volume, but the devil made the interface. Wolfgang Pauli. Robustness was in mind when designing the approach for handling damage at interfaces. Also, it should scale well. The applications are composites, but the main application is to model chip reliability.

Our new paper has been published. Conservative data-driven finite element framework with adaptive hp-refinement for diffusion problems with material uncertainty. doi.org/10.1016/j.cm...

This is for anyone who thinks they don't need to at least practice due diligence that output from an LLM is not copyright infringement or (obvious) plagiarism. (I contend it should be understood as both, even when the emitted text is not near-verbatim, because the mechanism is identical.)

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. youtu.be/DzbC4KG3XwU?...

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.

My talk at mfem.org/seminar (Lawrence Livermore National Laboratory) on the Mixed Finite Element formulation and MoFEM. Thanks to @tzanio.bsky.social for the invitation. It was a great pleasure.

📅 The next talk in our 𝗙𝗘𝗠@𝗟𝗟𝗡𝗟 seminar series will be on Tuesday, April 8th, 9:00-10:30am PDT. 🌟 Dr. Łukasz Kaczmarczyk (@likask.bsky.social) from University of Glasgow will present: "Mixed finite element formulation for solid mechanics problems". 👉 Sign up and learn more at: mfem.org/seminar.

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! openhub.net/p/mofem

Glasgow University can be also brutal.

Let's pray, mechanics. Mechanics have one dogma, and that is objectivity. Before the lecture in the old church.

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.

Sweet convergence. Works like a Swiss watch, but it might be better.

My internet at home is faster than at uni—a pretty sad fact in my line of work.

It was a pretty nice lecture room for the Structural Mechanics course in the Anatomy Thomson lecture room.

I'm playing more with Blender. HO elements and contact formulation in MoFEM, postprocessing glyphs in ParaView, and composition and rendering in Blender.

#MoFEM will always remain open-source. It is an incredibly great tool to test new finite element technologies.

As a result of DeepSeek, it is possible that politicians might implement export policies related to open-source, such as funding the development of national labs and research institutions. I do not know how, but it could be crazy—they might try to put the genie back into the bottle.

The words we heard from the main actors of the AfD rally about “Great Germany” and “the need to forget German guilt for Nazi crimes” sounded all too familiar and ominous. Especially only hours before the anniversary of the liberation of Auschwitz.

My new chair, with a pillow. That is a present from the company Mesh Oriented Solutions (MOS).

Today, I managed to learn how to render in Blender. Now, I need to learn the art of composition. ;)
