PHLAME: Pseudo-spectral Heat fLow using the Affine geoMetric heat flow Equation

Installation instructions for development

1. Clone the repo
2. cd PHLAME
3. Create a conda environment using the provided yaml file by running conda env create --name phlame -f phlame_env.yml
4. Activate the conda environment conda activate phlame.
5. Compile the pybinding: cd cpp/ and make. Note, This step will fail in Mac unfortunately.

Running tests

1. conda activate phlame
2. Add the modules to your PYTHONPATH using the following. Note in place of <your_phlame_directory> below make sure to use the full aboslute path to your phlame directory during the export:

export PYTHONPATH="<your_phlame_directory>/src/phlame":"${PYTHONPATH}"
export PYTHONPATH="<your_phlame_directory>/src/":"${PYTHONPATH}"

3. Run tests to verify correct installation
   • python3 installation_tests/scikits_odes_test.py
   • python3 tests/run_unit_tests.py
