NGSolve

Updates and News from the open source multiphysics finite element platform NGSolve. Some nice examples of how powerful FEM in Python can be :)

Check out the new #ngsolve #webgui! Online/offline rendering in the browser. Still work in progress, but already makes the tutorials more lively:

Let us know what you think about it!

[NGSolve @ng_solve]

Hi everyone, we will stream talks and tutorials from our Usermeeting starting this Sunday. For online participation just join the Livestream and ask questions .
The talks will also be later available for (re-) watch.

Pip installer for NGSolve are available now!
This means, installing NGSolve now becomes easy as

pip install ngsolve

Also works in venvs!

[NGSolve @ng_solve]

The 5th #NGSolve release of this year is available! Highlights are opencascade python bindings, new sections on shape and topology optimization in the i-Tutorials and improved web visualization.
We hope you try and enjoy the new features!

[NGSolve @ng_solve]

Open cascade Python wrapper now available in Netgen to create and modify geometries. Have a look at the new tutorials. We are eager to receive your feedback.
See here and following:

#NGSolve v6.2.2103 has been released and the interactive webgui has been integrated into the documentation.
https://t.co/YvkxSQgyQK

[NGSolve @ng_solve]

The first 2021 #NGSolve version has been released as v6.2.2101. Support for the M1 chip, linalg optimizations, bugfixes and a small new convenience feature: Double click in the gui on a drawn solution to get the solution values at that point in the console.

[NGSolve @ng_solve]

Support for the new Apple M1 chip is available on the current master branch. For installation instructions see here:

[NGSolve @ng_solve]

#NGSolve v.6.2.2009 has been released with 2D CSG support. To see how to define your geometries now easier see:

To download and install follow the instructions on

Another new feature in #NGSolve v.6.2.2008: get adjacent Regions easily. Getting the surfaces between air and iron is now as easy as: mesh.Materials("air").Boundaries() * mesh.Materials("iron").Boundaries()
@ngsolve

[Christopher Lackner @chrlackner]

Small new convenience #feature for #NGSolve: Easier definition of Region-wise CoefficientFunctions. Using mesh.MaterialCF({ "core" : 1000 }, default=1) or mesh.BoundaryCF(...). See for example https://t.co/HiocDj2L6F for an example use case. @ng_solve

[NGSolve @ng_solve]

#NGSolve v.6.2.2008 has been released, you can get it using the installers from https://t.co/yvVtFxqqie or using apt or conda!

[Joachim Schöberl @JoachimSchoberl]

@ng_solve we have a new preprint on mixed methods for non-linear elasticity available: https://t.co/SlFUiZg2OH. uses nice finite element spaces available in NGSolve

[Joachim Schöberl @JoachimSchoberl]

@ng_solve we have now the #newfeature MultiVector. It is an array of vectors, and matrix-vector multiplication and pair-wise inner products are well optimised. In #jupytertutorial https://t.co/97FXa6LTKw we show how to use it for simultaneous iteration for eigenvalue solvers.

[Joachim Schöberl @JoachimSchoberl]

@ng_solve we have some new #jupytertutorial on using MPI parallelization in #ngsolve. we show how to interface PETSc purely from Python: https://t.co/jOm473Ukkb
a #newfeature is the pickling of distributed meshes and gridfunctions.
