Nektar++ solver for Hasegawa-Wakatani equations

This repo contains a sample solver for the Hasegawa-Wakatani equations using Nektar++.

More details on the formulation are available in the brief documentation workbook.

Compilation & installation

The easiest way to build this solver is via Docker; from the top directory, build an image by running

docker build -t nektar-driftwave .

and then run an interactive shell with

docker run -it nektar-driftwave /bin/bash

If you have compiled and installed Nektar++ elsewhere, you can manually configure and compile this solver through CMake:

mkdir build && cd build
cmake -DNektar++_DIR=/path/to/lib/nektar++/cmake ..
make install

By default and unless a CMAKE_INSTALL_PREFIX is supplied binaries will appear in build/dist/bin. If Nektar++ is built with MPI, this will be supported in the DriftWaveSolver.

Running the enclosed example

Assuming that you are working from the shell in the Docker image, you can run the enclosed example either in serial or parallel as follows:

cp /usr/local/share/doc/nektar++/nektar-driftwave/*.xml .
DriftWaveSolver driftwave.xml square_quads.xml               # For serial execution
mpirun -n 20 DriftWaveSolver driftwave.xml square_quads.xml  # For parallel execution
