ngsPETSc

ngsPETSc is an interface between PETSc and NGSolve/NETGEN that enables the use of NETGEN meshes and geometries in PETSc-based solvers while providing NGSolve users access to the wide array of linear, nonlinear solvers, and time-steppers available in PETSc.

Installation

ngsPETSc is available on PyPI. If you have PETSc installed be sure to set the PETSC_DIR and PETSC_ARCH environment variables to the required values. You can install by running:

pip install ngsPETSc

Getting started

To get started with ngsPETSc, check out the documentation.

Development

If you already have NGSolve (with MPI support) and PETSc installed, you can install ngsPETSc via pip:

git clone https://github.com/UZerbinati/ngsPETSc.git
pip install ./ngsPETSc

Alternatively, you can also build PETSc, SLEPc, and NGSolve from source following the instructions in the documentation.

Testing

To test the installation, you can run the tests in the tests folder, via the Makefile in the root directory of the repository:

make test
