C++ library implementing Gravo MG. Gravo MG is a Geometric Multigrid Method for solving linear systems on curved surfaces. For more information, check out our [project page](https://rubenwiersma.nl/gravomg).

## Linking in CMake

You can add this library to your project by simply including the files in your folder for dependencies (e.g., by using git submodules or CMake fetch content) and then adding the subdirectory to your CMake file:

```cmake

add_subdirectory(deps/gravomg)

target_link_libraries([project_name] PRIVATE gravomg)

```

## Usage

Create the solver and construct a hierarchy:

```cpp

GravoMG::MultigridSolver(positions, neighbors, mass)

solver->buildHierarchy();

```

Solve a linear system

```cpp

Eigen::SparseMatrix lhs;

Eigen::MatrixXd rhs, x;

solver->solve(lhs, rhs, x);

```
