Drivers ======= The code repository contains several sample problems that can be found in the `drivers <https://github.com/sandialabs/PyNucleus/blob/master/drivers>`_ subfolder. The drivers take several command line parameters that can be used to change the problem and the type of outputs. A listing of parameters can be displayed by passing the `--help` flag: .. code-block:: shell drivers/runFractional.py --help .. program-output:: python3 ../drivers/runFractional.py --help Some of the drivers can be run in parallel using MPI, e.g. .. code-block:: shell mpiexec -n 4 drivers/runFractional.py --domain=disc runFractional.py ---------------- Assembles and solves fractional Poisson problems with infinite horizon. runNonlocal.py ---------------- Assembles and solves nonlocal Poisson problems with finite horizon. runFractionalHeat.py -------------------- Solves a fractional heat equation with infinite horizon. runNonlocalInterface.py ----------------------- A two domain interface problem with jumps in solution and flux for finite horizon kernels. brusselator.py -------------- Solves a fractional-order Brusselator system. runParallelGMG.py ----------------- Assembles and solves a classical local Poisson problem using geometric multigrid. runHelmholtz.py ----------------- Assembles and solves a classical local Helmholtz problem.
