petsc4Foam
General Description
Library for OpenFOAM that provides a solver for embedding Petsc and its external dependencies (i.e. Hypre) into arbitrary OpenFOAM simulations.
The library provides:
- ldu2csr matrix conversion.
- selection of solvers and preconditioners available in Petsc and in its external libraries (i.e. Hypre).
- editing of run-time options by a dictionary and/or a rc file.
- basic caching implementation of a Petsc matrix.
Requirements
- OpenFOAM-v1906 or higher or a recent development version from OpenFOAM.com.
- Petsc 3.10 or newer, optionally compiled with Hypre support (optionally with MPI support).
Building
Ensure that the OpenFOAM environment is active and that Petsc
can be found (check that the PETSC_ARCH_PATH environment variable is properly set).
Read How to build Petsc for OpenFOAM for more information
or visit the Petsc website How to build Petsc.
To install in the normal OpenFOAM directories (using wmake)
Simply use the supplied Allwmake script:
./AllwmakeThis will install the library under
FOAM_USER_LIBBIN.
