Introduction
Using the Spectral Einstein Code.
The Spectral Einstein Code (SpEC) is a flexible infrastructure for solving partial differential equations using multi-domain spectral methods.
Some of its features are:
- A flexible domain decomposition supporting individual subdomains (cells, elements) of various topologies, e.g. blocks, spheres, cylinders, and any combination thereof. Subdomains can touch or overlap.
- Solves hyperbolic and elliptic PDEs.
- Interfaces to the visualization software ParaView and VisIt.
External Software
SpEC benefits from the years of work put into the following general-purpose scientific software packages:
- PETSc: Parallel linear and nonlinear equation solvers
- SPHEREPACK: Spherical harmonic transforms
- FFTW: Fast Fourier transforms
- DFFTPACK: Double-precision fast Fourier transforms
- GNU Scientific Library: Mathematical routines for scientific applications
- Numerical Recipes: Numerical routines for scientific computing
