ThunderEgg is an object-oriented C++ library designed for flexibility and to allow users to implement parallel multigrid preconditioners for various problems on octree and quadtree adaptive meshes.
- Scott Aiton
- Donna Calhoun
- Grady Wright
- MPI
- CMake
- FFTW - FFTW PatchSolver
- BLAS and LAPACK - DFT PatchSolver
- PETSc - ThunderEgg provides a set of interfaces to use PETSc Krylov Solvers and PETSc matrices.
- p4est - for compatibility with the p4est quadtree library
Create a seperate source directory and run cmake in the build directory:
$ cd build_dir
$ cmake /path/to/source
Compilers can be specified in the following way
$ cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER /path/to/source
Then compile with make:
make
Some helpful CMake variables for configuration:
| Variable | Default Value | Description |
|---|---|---|
| PETSC_DIR | The PETSc directory | |
| PETSC_ARCH | The PETSc arch | |
| petsc | ON | allow the use the use of PETSc |
| petsc_required | OFF | fail if PETSc is not found |
| FFTW_ROOT | The fftw directory | |
| fftw | ON | allow the use the use of FFTW |
| fftw_required | OFF | fail if FFTW is not found |
| P4EST_ROOT | The p4est directory | |
| p4est | ON | allow the use the use of p4est |
| p4est_external | ON | build p4est library if not found on system |
| p4est_required | OFF | fail if p4est is not found |
| lapack | ON | allow the use the use of lapack/blas |
| lapack_required | OFF | fail if lapack/blas is not found |
