Finite Element Analysis rabbit hole.

#PrePoMax works passably on Linux and with youtube tutorials (thanks Indian- and Polish-accent guys) I could actually simulate twisting a rod and do experiments. Easy to use for a total newb!

That informs me where to place strain gauges for one of my projects.

I promise all the random stuff I've been doing ties together, eventually.

This is my latest article explaining why feminism needs NUPA.

Ever since the Supreme Court overturned Roe v. Wade, women's reproductive rights have been sitting in a highly polarized tumultuous limbo.

This piece moves past standard political slogans to address the core structural requirements of women—economic autonomy and medical safety—by treating them as hard-coded "fault-tolerance" layers within a deterministic operating system.

Бенчмарк аналитикой SCAD++, Lira и ammonit3d. Тест на точность с одним конечным элементом

В предыдущей статье "Облако своими руками для расчета пространственных стержней методом конечных элементов на Node js, React js и Three js" представлен краткий обзор облачного SPA приложения ammonit3d по моделированию пространственных стержневых систем (ферм, балок, рамных и связевых конструкций, опор ЛЭП) методом конечных элементов с численно-аналитическим решением для каждого конечного элемента, в основе которого математическая модель Эйлера-Бернулли - механическая модель упругой балки или стержня длиной L с заданной изгибной жёсткостью EJ на которую действуют сосредоточенная сила F или момент M, а также распределённая сила q(x) или момент m(x) по длине стержня, продольная ось которого x1, вертикальная x2 проходит через начало стержня и x3 направлена на нас из точки пересечения x1, x2. Полагая сечения плоскими до и после изгиба при одноосном деформированном состоянии в рамках краевой задачи линейной теории упругости, уравнение упругой оси стержня можно представить в виде обыкновенного неоднородного дифференциального уравнения 4-го порядка:

‎Vestido Rojo ❤️. Este es el primer vestido qué compré, para ajustarlo a mi altura lo quería estirar sólo un poco pero por error terminé dejándolo completamente liso y luego tuve que jalar los tirantes hasta que volviera a tener los pliegues.

Falda Negra y Medias Musleras Negras. Esta fotografía es de mi primera falda, cómo nunca utilicé una antes no sabía si la camiseta de tiritas iba dentro o fuera de ella, así que al final quedó así. En realidad era la primera vez de todo, camiseta de tiras, falda y medias musleras 😶.

@lwilde and I are currently planning to build a magnetron sputter setup. Since i learned that #freecad also is includes #FEM functions I want to try and model the magnetic field of the magnetron. I managed to get very simple geometries to work but quickly got stuck on more involved once.

Does someone know a nice guide which explains how to properly design 2D geometry for FEM simulation. Or maybe can explain to me what the operation in the red circle is, which is used in the examples?

Solving sparse finite element problems on neuromorphic hardware

As you solve partial differential equations without noticing with every move you make this is really useful problem solving #ai

As the number of people understanding #FEM (finitite element methods) actually is small this will not be exagarated as #llm.

Because there are more idiots who can talk than engineers who can calculate

If one has a linear-elastic material in mind, one would assume this works for any kind of finite element simulations. In case of large rotations and large strains, "linear" is not unique. There are many different implementations of linear-elastic materials. Beside the mathematical details, a cube, rotated by 90° and stretched to a factor of 2, will show different deformations. You'll see a small-strain, Total-Lagrange (Saint-Venant Kirchhoff material) and the co-rotated framework as well as a compressible Neo-Hookean material model formulation.

Reminder: don't use small-strain linear-elastic material formulations in simulations where large rotations occur - just because the strains are "small".

idk what #fem #trans #person needs to hear this but you should get a #winter skirt. get a thick long wool skirt. or else you will find yourself with only thin warm weather skirts and then be either freezing cold or dysphoric come winter. do not do that to yourself. invest in a heavy warm skirt and then you can frolic through the snow in style and comfort

Our most recent paper on #SPH / #FEM coupling for offshore structures modeling with #GPUSPH has been published:

These kinds of works, with validation against experimental results, is always a challenging task, even for the simpler problems. Lab experiments and numerical simulations have each their own set of problems that need to be addressed, and the people working on the two sides of the fence often have a very different perspective on what should be considered trivial and not worth measuring, and what is instead crucial to the success of the experiment.

Getting these two sides to talk to each other successfully is no walk in the park, and I wish to extend my deepest gratitude to Vito Zago, who has gone to incredible lengths both during the “science making” to make things work out, and during the manuscript submission and review process, a nearly Sisyphean task in itself.

I Wonder where the #hearingaids developers are! These would be awesome to have do a talk.
Same for the "process signal, but *fast*" people; top of my head, we've got @rygorous , but he's more on the "fast" than on the signals side. We have @mkretz who could talk about C++ SIMD stuff, but my guess: he'd prefer to talk in a room full of compileristas?
Are #EMerge #FEM/#Heavi people here? It'd seem #Sionna gets a lot of well-deserved attention combing physics+signals, but it's not the sole toolkit!

I made a #streamlit app for a nonlinear #fea simulation of a deformable hyperelastic solid body. This uses #FElupe for the simulation and #pyvista / #stpyvista for showing the final result in your browser.

What’s new in FEM for FreeCAD 1.1?
Now that the feature freeze for FreeCAD 1.1 is on, and we are not too far off from the final release, let’s summarize the main changes in the FEM workbench. Just like in the case of the revolutionary 1.0.0 release (see this blog post), FEM dominates the release notes. There have been many significant improvements, so let’s go through them.

#DevelopmentUpdates #FEM

After a summerbreak, #FElupe development continues! Stay tuned for lots of handy new features: checkpoint/restore, revolve a.k.a. axi-to-3d, simplified handling of multiple solid bodies, etc. These new features are already available in the main git branch and will be released soon.

P.S. I'm always open for new ideas, just let me know!

САПР «ГАММА»: российская альтернатива для проектирования СВЧ-электроники

Импортозамещение в области систем автоматизации проектирования стало новым технологическим стандартом. Особенно остро этот вопрос стоит в высокочастотной электронике. Проектирование компонентов, работающих в диапазонах сверхвысоких частот, требует точности, моделей, верификации и совместимости с оборудованием. Отказ зарубежных вендоров от поставок или обновлений ПО поставил многие проектные группы в тупик. Но у отечественной промышленности есть свой ответ. Им стала
