What is Afivo?
Afivo is a generic framework for simulations on adaptively refined quadtree and octree grids [afivo_paper]. Some key features/characteristics of the framework are:
- Adaptively refined quadtree and octree grids
- OpenMP parallelization
- Geometric multigrid routines
- Flexible handling of refinement and physical boundaries
- Silo and VTK unstructured output
- Written in modern Fortran
- Open source
Installation
See the installation instructions, afterwards have a look at the examples.
What is included?
Afivo provides general functionality for parallel simulations with adaptive mesh refinement:
- It can adjust the refinement according to user-supplied information
- It stores cell-centered and face-centered variables
- It provides routines to perform restriction and prolongation (to convert fine grid values to coarse ones and vice versa)
- It can fill so-called ghost cells, which allow the user to perform computations as on a uniform grid
- It can (help) solve elliptic partial differential equations with the built-in multigrid methods
- It can write output in Silo and VTK format, which can directly be visualized with tools such as Visit
See the Modules page for all included modules. Have a look at the Documentation contents to get started with Afivo.
