Elegant solution, I like it.
Thanks!

Bruno,

I don't think we have a function that would do that already. I would just
loop over all (locally relevant) cells, and add the respective (locally
relevant) dofs to the AffineConstraints object with add_line().

Best,
Daniel

[deal.II] Applying a zero constraints to cell based on material_id

2022-10-31 Thread blais...@gmail.com 
Dear all, I hope you are all doing fine :)!

I am trying to do some quick testing of something and this would require me 
applying a zero constraint to a set of cells which have a specific material 
id. I could surely do that from the weak form, but I was wondering if there 
was a way to do it strongly by applying a constraint like we do with 
boundary conditions (e.g. using VectorTools). I looked around in the 
documentation but I could not find anyway (but maybe I did not look 
carefully enough).

Thanks!
Bruno
