pressio-demoapps is a library of 1D, 2D and 3D demo problems of varying complexity, ranging from a simple 1D linear advection, to 2D reaction-diffusion, and 3D Euler equations, and more.

Key features include:

• support for both C++ and Python
• cell-centered finite volume discretization with various numerical schemes and exact Jacobians
• focus on providing self-contained and well-defined problems
• built-in support for a sample mesh: this mean that one can evaluate the residual and Jacobian at a disjoint subset of the mesh cells (this is useful for intrusive ROMs, but in general for other purposes too)

pressio-demoapps is planned to be maintained in the long-term. Hopefully, more problems and features will be implemented. If you are interested in collaborating or would like to see a specific problem added, please reach out.
