## libCEED deal.II Example

An example how to write libCEED operators (BP1-BP6) within the open-source finite element library [deal.II](https://www.dealii.org/).
As reference, operators are presented that use the native matrix-free infrastructure.

First compile deal.II and libCEED individually. After that, compile the deal.II example:

```bash
mkdir build
cd build
cmake ../ -DDEAL_II_DIR=~/path/to/dealii -DCEED_DIR=~/path/to/libceed
make
```

To run the executables, write:

```
./bps_cpu
```

```
./bps_kokkos
```

Optional command-line arguments are shown by adding the command-line argument "--help".
