# prop

FDTD solver of Maxwell's equations with the use of different backends including GPU.

While computational part is written in c++ you are encouraged to use `python` wrapper to execute calculations and handle

data.

# Build

`prop` uses `cmake` for compilation and relies on CPM to fetch external packages.

Example command to build prop with openmp support, to compile with CUDA support, use `prop-cuda-debug` preset.

``` sh

cmake --preset prop-openmp-debug

cmake --build build --target pyprop

```

IMPORTANT: please specify `target` when building `prop` otherwise compilation time will be extremely large.

Include target `prop_test` if you want to run unit tests.

You can see all available presets via `cmake --list-presets` command.

# Usage and Examples

You can find examples in `examples` folder. `prop` provides cmake target `copy_python_files_in_binary_dir` to run examples without installation of python package system wide.

``` sh

cd build

cmake --build . --target copy_python_files_in_binary_dir

python ./simple.py

```
