[Dune-devel] Non linear mechanics, Dune, MFront

[Dedner, Andreas]

Hi.
Mechanics isn't my main area of research but I'd be happy to provide some help where I can. I've been working on Python bindings for Dune's C++ frontend which have a lot of similarity with Fenics' approach. So we use UFL to define the models and use high level bindings to assemble system matrices etc.
Since you are already working on Fenics bindings doing something similar with Dune should not be too difficult I would hope. I have myself transferred some (quite simple I must admit) examples from Fenics to Dune. An overview of what is available and what it looks like can be found here
https://dune-project.org/sphinx/content/sphinx/dune-fem/
If that looks like a useful starting point and if there is something specific you encountered with Fenics that was helpful/difficult to handle let me know.
Best
Andreas

Subject: Re: [Dune-devel] Non linear mechanics, Dune, MFront

Dear Olivier, Christian, and others,

As a first step, I plan to build a simple tensile test on a unit element and
see how I can interface MFront with it, probably using the MGIS project
(https://github.com/thelfer/MFrontGenericInterfaceSupport). I expect that
if I manage to get this working, I will have a global overview of DUNE
internals and will be able to use any MFront behaviours in real-work
structural cases.

To do this, I am currently reading the dune-fem introduction. If anyone has
some documentation of what is already available in the non linear mechanics side,
let me know, it may save me a valuable amount of time.

I hope to be able to grab my hand on dune rapidly, once I will have overcome a little trouble with the source
installer (for the moment I wish to report this trouble, but I have not found what is the most relevant project in
which opening the issue, as the installer is hosted on a private repository).

Regards,
Thomas

Hi Thomas,

while I don't use code generation at all, I work in nonlinear mechanics,
so what you plan is of interest to me.

Best,
Oliver
