FDSolverPy

Parallelized finite-difference module for solving physics problem.

Installation

The installation time is typically within 5 minutes on a normal local machine.

Dependencies:

• numpy
• mpi4py
• matplotlib

An example for the installation process:

To install FDSolverPy, clone this repo:

git remote add origin [email protected]:bumpwy/FDSolverPy.git

and run:

pip install -e /path/to/the/repo

The -e option allows you to edit the source code without having to re-install.

To uninstall:

pip uninstall FDSolverPy

Test run

Examples can be found in the ./test directory. For instance, under ./tests/local/2d/microstruct contains examples for diffusion problem in a microstructure.

./run.py

and to plot the results do

./plot.py

and you shall obtain

where $d(\bf{r})$ is the polycrystalline diffusivity, $\Delta c$'s are the perturbative concentration fields for driving force in $Q_0 = (1,0)$ and $Q_1 = (0,1)$ directions.
