[deal.II] how to get the transpose of a block sparsity matrix?

Dear all deal.ii users, I am studying goal oriented adaptivity for FSI problems and code it in deal.ii. The system consists of velocity, pressure, displacement(u,p,w), so I use block sparsity matrix for system matrix. When I solve the dual equation, I find what I need is a transpose

Re: [deal.II] Re: Application for the use in continuum mechanics

Dear Lucas, As a by-product of my worked I have implemented (or, rather, I am implementing) something similar to what you describe, though the focus is not on mechanics alone, but rather on coupled problems. Essentially, the library I have written is solving problems where a possibly non-linear

Dear All, We currently have an open position in my research group regarding the computational modeling of microwave depolymerization reactors using deal.II. These reactors are part of a key technology that enables the generation of virgin styrene monomers from contaminated polystyrene using

Hey Alberto, thanks for the response. PRISMS-plasticity seems to be really interesting for me. I might have somehow overlooked the application when I was searching the dealii page. Anyway, it would also be interesting to take a look at your coe if you would be so kind to share it with me.

Hey Lucas, sure, just contact me directly at lukas.l...@ifam.rwth-aachen.de Since I am also working on growth processes, getting in touch might be interesting for both of us. Best regards, Lukas -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see

Re: [deal.II] Re: Application for the use in continuum mechanics

HI Lukas We at m4lab (m4lab.unibs.it) have been writing a Constitutive model library and a set of “steps”, with the same style of deal.ii steps 18 and 44. So far, we did not made them public but if this may interest you we can definitely share the code and then will see. Did you look into

[deal.II] Re: Application for the use in continuum mechanics

Dear Lukas, I fully understand your point. No need to reinvent the wheel. I don't know any such software. However, if this is the whole change you want to do, tutorial-44 seems indeed to be a suitable start for you, even if this is a somewhat complicated program. > where you can e.g. easily

[deal.II] Re: Application for the use in continuum mechanics

Hey Lucas, thanks for your response. I was actually searching for some application somehow similar to FE software like e.g. FEAP or Deadalon, where you can e.g. easily implement any desired material model but do not have to care about the whole assembly and solution process. At least not if

[deal.II] Re: Application for the use in continuum mechanics

Dear Lukas, I am working with Continuum Mechanics, although I would not call my research "more advanced" than the stuff in tutorial-44, at least from a computational point of view. Mostly, growing materials. Could you be a bit more specific on your needs? Bests, Lucas On Thursday, 15 August
