Hello,
I am developing a nonlinear CSD code with FEM. I tried to use GMRES in Hypre to solve the linear system. Before adding the subroutine to my CSD code, I have added it to a FEM based CFD code a…

These are the characteristics of an AMG implementation highly optimized to solve the p equation matrix resulting from external flow problems (CFD):
Characteristics:
- Requires positive…

Thanks for making this library available, it's been very useful for my work!
I've found that `p8est_coarsen_ext` often coarses families of quadrants that should not be coarsened and they get refine…

Dear @ddemidov,
Thank you for creating amgcl! I've been using it to solve the electric potential Poisson equation in a particle simulation and the performance has been quite impressive. However, rece…

I am testing FGMRES preconditioned with classical AMG on a Poisson matrix (2D unity square, 5 point stencil, 1000 elements, 1.000.000x1.000.000 matrix)
I ran the solver with the following json file…

Hello there, firstly congrats on this AMR framework you maintain. :+1:
I'm a senior programmer of an AMR code that's been in constant development for the last 14 years in Brazil. We have very well…

Hello Denis,
I tried to update an interface with the latest version of AMGCL to work with mixed precision etc. all MPI but I get a few compile Errors even before making changes:
This is the code…

Hi,
Now that levelset classes are not present in the latest amrex, I am trying to use this helper function but has
not been successful in getting the right levelset when using a higher refinement …

Sir, thanks for your great job of amgcl.
I was using Eigen CG to solve the linear system, it not fast enough so I come to amgcl.
My matrix `A` and vector `f` comes from 3D solid finite element m…
