Hi I am trying to solve a complex number system with the ILU0 preconditioner (single level), the declaration is
```cpp
typedef amgcl::backend::builtin< std::complex > Backend;
typedef amgcl::make…

I have a program that I run multiple times. Each time the program runs it uses the same linear system `A` and solves `Ax=b` (using AMGCL) with a different right-hand side. Therefore, every time my p…

I tested 02-channel-block-flag_2D with svFSIplus and found the residual blew up w/ or w/o Trilino preconditioner ILUT.

I'd like to implement an additional preconditioner for SPD/symmetric matrices i.e. to solve the pressure equation:
There are several candidates but they have many similarities from an computational…

These maps and string things can potentially move into the library. In fact, I made something similar a few months back. [see inline std::string nonlinearName(const NonlinearSolver& s)…

Hello,
I am exploring using Hypre in my application and I am particularly interested in its GPU capabilities:
- Which of the solvers and preconditioners in Hypre are available on the GPU? I am…

Currently, `preconditioner::Ilu` has some shortcomings, as it only supports ILU(0), doesn't allow setting factorization parameters, needs multiple template parameters to statically ensure equal `value…

For some problems, left preconditioner i.e., solving MAx = Mb instead of Ax =b (M is the preconditioner) works much better than using right preconditoner.
However, by default all preconditioners i…

Hi,
I intend to implement Euclid preconditioned flexible GMRES in my Fortran code. However, I could not find the precond ID for Euclid preconditioner required in HYPRE_ParCSRFlexGMRESSetPrecond sub…
