Dear Denis,
I really would like to thank you for open sourcing such a well designed and super flexible framework to play with AMG:)
I was working on a project on multigrid recently, and tried to…

I'm trying to use AMGCL to solve a simple Stokes problem using finite element method. The linear system is similar to Naiver-Stokes one:
[K G * {u = {b_u
D S] p} b_p}
2nd Order FEM…

Hi,
As @anne-glerum already mentioned it in the issue [#3402](https://github.com/geodynamics/aspect/issues/3402), using the initial topography can caused the mesh to have holes in it (see figures).…

We've been considering cleaning up the IO operations for a while. (As referenced in #88) Since we are consolidating the overall workflows, it's probably time to address this. I believe we've centere…

Sir, I want to solve many right-hand sides. I want the grid hierarchy only to be created once.
What I want can be expressed using follow pseudocode.
```
SparseMatrix A;
Vector b1,b2,b3;
Solver s…

It would be useful to have the ability to specify the coarsening function used in the `coarsen_restarts` dataflow workflow. Right now there are two available functions with the same interface, `coars…

I have two example meshes with a sideset and nodeset either on the top of the domain or left side of the domain

Hi Denis,
Thanks for your work about this open source package. I am a student working on solve large dense linear system (i.e. Ax = b where A is dense and large). I wrote my own iterative complex g…

I'm currently extending the tmLQCD QUDA interface to provide access to the multigrid solver and its parameters. While the gamma basis problem still exists, I currently "fix" this by forcing `QUDA_DEGR…

I have run your code, but I found that it did not coarsening the graph. I try to find out the reason, it leads me to the sfdp, the method you use to coarsening the graph. Since I can not find any usef…
