[en] FEniCSx Preconditioning Tools (FEniCSx-pctools) is a software package for easing the specification of PETSc-based block preconditioning strategies in the DOLFINx finite element solver of the FEniCS Project. It attaches all of the necessary metadata to the block-structured linear systems in order that block-structured preconditioners can be applied straightforwardly via PETSc’s options-based configuration system. Fast prototyping is facilitated thanks to the implementation in Python, and all intensive operations are executed in C/C++. FEniCSx-pctools is available under the LGPLv3 or later license.
