Monolithic coupling, staggered coupling, multiphysics capabilities

[Saman Seifi]

Hi all,

So I have developed an explicit-implicit staggered model for studying electro-active polymers under electrical or/and mechanical loading. I already coded the model in Tahoe (an old C++ FE code from SANDIA) and published the result. I want to implement the same formulation in deal.ii, but I'm not sure how to do it. Is anyone have any experience in coding any multiphysics models? monolithic implicit, staggered implicit-implicit, or explicit-implicit?

Thanks

Saman

There are many examples of multiphysics codes out there (you might want to
look at Thomas Wick's Fluid-Structure Interaction code, for example, that was
published in the Archive of Numerical Software). So it's possible for sure.

You might have more luck on this mailing list if you asked concrete questions
about issues you're stuck with. There is no good answer to "I'm not sure how
to do it" :-)

Best
W.

To add to what Wolfgang said, there are a multitude of papers in our publication list

https://dealii.org/publications.html

that mention electro-active polymers and magneto-active polymers. You might wish to look there to see what has been accomplished in these research areas using deal.II.

Best,

Jean-Paul
