Notebooks

For the documentation, we provide several Jupyter notebooks that illustrate how to use PSYDAC to solve different types of problems. They can be found in the notebooks directory, but are also generated as part of the documentation and can be accessed here:

Notebooks:

• Solving Poisson’s equation on a square domain with a mapped grid
• Solving Poisson’s equation on non-periodic topological domains
• Solving Helmholtz’s equation on non-periodic topological domains
• Finite element projections of scalar and vector-valued functions
• 3D example with VTK and ParaView
• Example of computing approximative eigenvalues with PETSc
• Example of solving the curl-curl eigenvalue problem
• Solving the time-harmonic Maxwells equations on a multipatch domain
• Computing the vector potential of a solenoidal field on a Torus

FEEC Examples

In the FEEC examples directory, you will find several examples of how to use PSYDAC to solve problems arising within the Finite Element Exterior Calculus (FEEC) framework. These examples include:

• Poisson problems

• General curl-curl eigenvalue problems

• Time-harmonic Maxwell equations with source terms

• Time-dependent Maxwell equations

Performance

There are also some examples in the performance directory explaining the assembly algorithms used in PSYDAC.
