Helmholtz

AMG Helmholtz project with Achi, Oren, James, Jacob and Ahsan.

Contents

• src: source code.
• src/helmholtz: Python Helmholtz code.
• src/test: unit tests.
• notebooks: Juypter notebooks.

Installation

• Install conda.
• Create a conda environment from the attached environment.yml: conda env create -f environment. yml.
• Add src to your PYTHONPATH.

Testing

The project contains Pytest unit tests for the main modules. To run all tests, run cd src; pytest test.

TODO List

• Add Ritz projection. For now save only the smallest lam and enough x's that match x's original shape.
• Calculate multiple eigenpairs.

Done

• Replace GlobalParams by passing the lambda array with x from level to level within the cycle.
• Automatically increase aggrgate size until a good coarsening ratio is obtained (small kh: 2, large kh: 4).
• Replace many x columns by few x's and many windows to fit the restriction.
