Hello everyone,
Is there a reliable way to get the natural logarithm of a symmetric
positive definite tensor in deal.ii? I'm trying
`LAPACKFullMatrix.compute_eigenvalues_symmetric`, taking the `std::log` of
the eigenvalues and then multiplying by the eigenvectors appropriately:
const Symmetric
Hi Shahab,
Adding to Luca's reply you probably want to look into the `ParticleHandler`
class, in particular the `particles_in_cell` function that returns you all
particles in a given cell

Hi,
That's unfortunate.
Thank you for the reply
Bye!

Dear David,
sorry, macOS Mojave (and further Catalina) do not have candi support -
there is something strange happening
in the recent past with the base compilers and homebrew installed mpi
compilers.
(I had a similar problem as you reported)
Currently I recommend to install the deal.II toolch
Hello everyone!
I'm trying to rewrite Step-35 (Navier-Stokes tutorial) without splitting
the implementation for component (In Step 35 one thread resolve the x
component and the other one the y component).
Proceeding in this way I can use "AffineConstraints" class to manipulate
constraints in
