@chenna1985 @fenicsproject I see. There is old documentation kept in https://t.co/dAJuKQqcLM and often Google ranks version 1.6.0 (quite old) as highest in search results. FEniCSx (recommended over the legacy FEniCS) has documentation under https://t.co/U5o1ZP8FRm.

@JustinMSolomon You cannot have this relation for arbitrary matrix, as any equality of form exp(A) ~ mexp(A) would be "equality" of two objects that transform very differently under change of coordinate basis (similarity). Trivially, it holds for small perturbations of diagonal matrix.

@LukaszKaczmarcz @peter_grassl @GCEC_ @UK_ACM Is post-dock a name for short-term post-doc positions? But seriously, the link/page is broken.

AceGEN + @fenicsproject news! With @MHabera in @uni_lu within @MSCActions we plugged efficient code for large-deform. elasto-plasticity + non-linear hardening into the multistep N-R scheme, all running MPI parallel with PETSc as linear algebra backend and MUMPS direct LU solver.

Also do not import with wildcards (from abc import *) in python.

[Joel Yliluoma @RealBisqwit]

Sure, you can do “using namespace std;” in your program. It is about as smart as removing the driver-side door in your car, because it is so redundant having to open & close it every time you start driving.

The best AD system AceGen + highly efficient FE system @fenicsproject = unlimited possibilities. Today in @uni_lu , together with @MHabera, first time in history we established the interface between the two systems🍾 This makes a great example of synergies enabled by @MSCActions

I always wondered who is the guy with initials "NB" that touched so much code... Nota Bene that NB aren't initials.

- yes, I saw your email, why?

[Michal Habera @MHabera]

Amazing how an "algorithm" could be encoded into a polynomial. And magical word "nonnegative values" then triggers the machinery :)

[Robin Houston @robinhouston]

I was fascinated by this theorem as a teenager, and I still find it remarkable.

Just wow...

On the relation of Ricci curvature, optimal transport, gradient flow and entropy.

[Michal Habera @MHabera]

Beautifully explained, simple and enlightening. https://t.co/sExpCi9O6M
